If we fail to meet the service levels outlined in your SLA contract, such as taking longer than the specified time to resolve an issue, you are eligible to claim SLA credits. You can initiate the claim process by filling out the form on our SLA claim page. Ensure to provide all necessary details about the service issue.

To check if your services are covered by an SLA or to upgrade your SLA, you can reach out to our account managers. They are more than happy to outline your current SLA coverage and discuss options for upgrades to meet your specific needs. You can book a meeting with your account manager here.

Yes, an SLA contract is tied to each individual internet line. Therefore, you will need to sign an SLA for each site where you have an internet line to ensure coverage and service quality at every location.

We usually do not transfer SLA credits to your bank account. Instead, we issue a credit notice and deduct the amount from your next month's invoice. This method ensures that your account balance is adjusted accurately and efficiently.

Once you fill out the form on our SLA claim page, we strive to process your claim as quickly as possible. Typically, it takes us between 2-3 weeks to analyze your claim and issue the credit notice. This time frame allows us to thoroughly investigate the reported issue and ensure accurate credit issuance.

Mixvoip does not provide router access by default but grants full administrative rights for free upon request, allowing customers complete independence in managing their IT and internet security. For connections like copper DSL and coax, a modem might be necessary; however, the setup remains transparent. Customers may also configure their own devices using provided PPPOE credentials or fixed IP parameters depending on the connectivity service selected.

For selecting internet bandwidth, it's generally recommended to start with at least 1 Gbit/s, especially for businesses utilizing cloud services. If higher bandwidth is available at your location, opting for more can enhance productivity and prevent slow internet from impacting your operations. This recommendation applies both to large enterprises and SMEs, where the demand for bandwidth is consistently growing.

Mixvoip ensures each customer receives a unique, dynamically allocated IPv4 address by default, with no sharing of IP addresses or use of carrier-grade NAT. For a nominal fee, this can be upgraded to a fixed IPv4 address. We adhere to strict net neutrality, blocking no traffic to provide the purest internet experience. IPv6 blocks are also available at no extra cost.

While mobile connectivity over 5G or satellite may not match the reliability of fiber lines, it is comparable to or better than slow or poor-quality copper DSL connections. These options offer higher speeds and can be a reliable alternative in areas where traditional wired internet is not feasible.

Internet routers are often installed in locations with poor mobile connectivity, such as underground rooms, metal racks, or the interior of buildings. Modern building materials can also hinder mobile signals. To ensure optimal connectivity, we provide a separate mobile router that can be placed outdoors or in areas with better signal reception. This approach allows for reliable 5G connectivity where it is most effective.

The MTU (Maximum Transmission Unit) size for the 5G service is set to 1420 bytes. This is slightly less than the standard 1500 bytes.

There are two setups for the 5G backup activation: automatically, where our router detects an internet downtime on the primary line and switches to the 5G backup, or manually, by rerouting traffic on your firewall to the 5G router to initiate a failover.

The 5G Backup service provided comes with unlimited data usage, ensuring continuous and unrestricted internet connectivity.

We do have different internet packages for individuals. You can find all our internet offers directly on our Residential page.

The "monitoring and alerting" feature specifically tracks the real-time status of your network connectivity, sending alerts for any disruptions to ensure quick resolution. "Bandwidth graphs" visually represent the usage of your network's bandwidth over time, helping you monitor traffic patterns and manage network capacity effectively. Together, these tools are crucial for optimizing and maintaining reliable internet connectivity.

"Support hours" refer to the times customer service is available to help with general inquiries and support issues. "Fault processing hours" are specifically for technical teams to address and resolve service faults or disruptions, typically offering extended time slots to ensure you are never without internet.

Perform a Speed Test: We recommend starting by conducting a speed test on your line. Since the speed can never be guaranteed with a wireless connection (such as WiFi), please connect your computer to the router using an Ethernet cable. 1. Visit the Speed Test Website: Go to www.speedtest.lu and click on the"BEGIN TEST" button. Wait for the results to be fully displayed (PING, DOWNLOAD SPEED, UPLOAD SPEED). 2. Interpret the Results: YES: If the results match the speed of your Internet subscription, the speed issue does not seem to come from your line. Please check your computer hardware and settings. NO: If the results do not match the speed of your Internet subscription, please restart your router.(unplug the power from your router for a few seconds and then plug it back in)

Yes, upgrading your Emios Internet Line to a higher speed is easy. Just reach out to our sales team, and we can plan the upgrade without any intervention. Please note that in some scenarios, you might need to upgrade your router or choose a faster router from our managed router model to fully benefit from the increased speed.

Not all Emios Internet packages are fiber-based. Some buildings are not yet connected to the fiber network, and only DSL may be available, offering speeds below 100 Mbit/s. You can verify the available options for your address using our internet search page. The fiber network is expanding quickly, so availability may improve over time.

Although support for telephony, local network, and Wi-Fi is not included in our retail internet packages, we offer specialized packages tailored for the unique needs of shops, restaurants, and salons. These packages come with very competitive pricing and provide support seven days a week to cover all your communication needs.

Our Retail internet packages, tailored for the demands of retail business operations during weekends and peak periods like Christmas, offer extended support hours and quicker intervention times, available seven days a week. These are designed to ensure reliability during critical business times, unlike our standard fiber options which cater to general needs with more affordable pricing.

Absolutely! Whether you need a brand-new mobile number or wish to keep your current one, we've got you covered. We offer new mobile numbers and can also handle the porting process to transfer your existing number to our services, ensuring a smooth transition.

At Mixvoip, we understand that your needs can change rapidly. Whether it’s for working from home, faster video downloads, or online gaming, we’re here to support you. Whatever the reason, we can upgrade your internet connection whenever you need, ensuring you always have the speed and reliability you require.

The contract duration of a new internet line is 2 years.

With our internet installation packages, we can provide you with a Fritzbox for your connection. However, our technicians are trained to work with a wide range of modems. This gives you the flexibility to choose the modem that best suits your needs, and we’ll ensure your internet line is set up properly on the device you select.

If you already have internet with Mixvoip and you are moving, you only need to contact our experts here, they will contact you back to plan everything, to make sure you have the new internet line when you need to.

Yes, we offer highly redundant internet lines that enter the building through different paths. Many business premises can be connected via multiple routes, and we supply the fiber route maps, known as KMZ or KML files, for complete transparency. The internet lines can be set up to terminate on either separate routers or a single router. By using BGP (Border Gateway Protocol), we enable dynamic failover and manage redundancy effectively.

Businesses often require the same upload and download speeds due to applications like video conferencing, data backups, and large file transfers. A symmetrical setup, though potentially more costly, avoids bottlenecks and should be considered for businesses with more than 20 users. Investing in a symmetrical connection ensures efficient data handling, minimizes latency, and supports consistent performance.

The bandwidth on DIA (Dedicated Internet Access) lines is dedicated, not shared. These are point-to-point connections, meaning a specific portion of fiber is reserved exclusively for your use. Unlike shared technologies like X-GPON, DIA lines ensure consistent performance and reliable connectivity, as your bandwidth is not affected by other users.

To migrate your configuration, follow our step by step guide. In a rush? Here’s a summary: 1) update Voxbi Legacy to the latest available in the store; 2) open the latest version of Voxbi Legacy at least once; 3) only then install and open Voxbi 2.

Send and receive faxes by email With our cloud PBX solution, send and receive faxes directly from your email account. If you have a fax machine, with an analog to IP converter, you can send faxes and receive them. However, the full transmission cannot be guaranteed for technological reasons detailed below. Is The Fax Dead – Read The Article ALTERNATIVE SOLUTIONS TO FAXES In most European countries, all telecommunication players have agreed to gradually replace the switched telephony technologies with ALL-IP ones by 2025. Today the use of a fax machine in a VoIP environment remains possible, but according to Règlement ILR dated 9th of August 2017, ‘‘there is no guarantee of end-to-end interoperability’’ (ILR/T17/9) As Voice over IP technology is optimized for voice transport, fax transmissions cannot be guaranteed anymore, by any operator. E-SIGNATURE In some cases, faxes have a legal value. This is why, the electronic signature is the best alternative at the moment. At Mixvoip, we developed our own module with an electronic signature. sign.mixvoip.com Customers can fill, sign and send their documents online. They have a legal value. The document will be also sent by email to the customer at the email address they provided.

Create a new mail where the recipient is the FAX number followed by the domain @ufax.eu, attach a PDF file in A4 format, and paste your Fax key provided by Mixvoip in the subject or in the message body. Recipient: NUMBER@ufax.eu (number must be numeric and can look like 004969… for international calls or 20333390 for national ones for example) Subject: fk:XXX-XXXXXXXXX The PDF file must be in A4 format 210 x 297 mm (21 x 29,7 cm) Features and limitations FAX key is only usable from the same domain as the email address shown on the page you retrieved the FAX key from • Supports 1-5 documents per e-mail • Supports up to 5 different recipients • Supports PDF • Documents should be in portrait, not landscape format FAX key Your FAX key can be retrieved from our web interface in the user settings section. This page is accessible by going to the ‘User management’ menu and clicking on the username you want to send a fax from. Technical details The fax key is a 9 characters long sub-string of the concatenated md5 hash of the username, password, and the suffix string “faxkey”, prefixed by the user’s account code. $faxkey=$accountcode.'-'.substr(md5($username$password.'faxkey'),0,9);

When a call comes into your group, it rings your extension, which is then forwarded to your mobile. If your mobile has voicemail enabled, the call can be intercepted by your voicemail if it picks up before you do. Since the system can’t distinguish between a person answering and the voicemail picking up, the call is treated the same way. To prevent this, you can either disable your mobile voicemail completely or extend the voicemail delay to be longer than the group’s ring time. The best solution is to completely disable your mobile voicemail.

Voxbi Mobile is a fixed-mobile convergence app, so calls are forwarded to your mobile. A notification is typically sent before the call, but it's not always reliable due to the way phone's OS handle notifications. To reliably differentiate, you can use a dedicated eSIM for Voxbi calls. Two alternative options : 1. eSIM Icon 2. eSIM Ringtone

Purchasing services directly from infrastructure providers often lacks the personalized service and customer support that Mixvoip offers. Beyond just providing connectivity, we add value with tailored solutions, expert support, and integrated services to meet specific business needs. In a business environment, comprehensive support for not only connectivity, but also network issues (including LAN and Wi-Fi), is crucial.

Installing our own cables isn’t feasible due to the enormous logistical, economic, and ecological challenges it would present. It's more practical and sustainable for local infrastructure providers to build and maintain these networks. This strategy prevents redundant infrastructure, which would be economically inefficient and ecologically unsound. Instead, by accessing these existing networks, Mixvoip focuses on delivering added value through our telecommunications services, ensuring customers receive high-quality, cost-effective solutions.

Non-compliance can lead to legal consequences, including fines and other penalties. Moreover, non-compliant companies may face heightened risks related to employee grievances or reputational damage, underscoring the importance of adhering to these regulations.

Certain exceptions and flexibilities are permitted and integrated into labor laws. For example, specific industries or job roles (such as emergency services or seasonal work) may be subject to adapted requirements. However, these exceptions must still prioritize employee safety and well-being.

The directive sets out several key requirements: • Maximum weekly working hours: Employees should not work more than 48 hours per week, on average. • Daily and weekly rest periods: Employees are entitled to a minimum daily rest of 11 consecutive hours and a weekly rest period of at least 24 uninterrupted hours. • Paid annual leave: Employees are entitled to a minimum of four weeks of paid annual leave. • Breaks: Employees have the right to adequate breaks during working hours, especially if their workday exceeds six hours.

EU member states have incorporated the requirements of Directive 2003/88/EC into their national labor codes. These regulations address key provisions such as maximum weekly working hours, rest periods, and minimum paid annual leave. Employers within the Union are required to comply with these laws to meet both national and EU standards.

Yes, the European Working Time Directive 2003/88/EC is mandatory in Luxembourg. As an EU member state, Luxembourg is required to align its national labor laws with this directive, which establishes minimum standards for working hours, rest periods, and annual leave to protect workers’ health and safety.

Certain exceptions and flexibilities are permitted and integrated into labor laws. For example, specific industries or job roles (such as emergency services or seasonal work) may be subject to adapted requirements. However, these exceptions must still prioritize employee safety and well-being.

The directive sets out several key requirements: • Maximum weekly working hours: Employees should not work more than 48 hours per week, on average. • Daily and weekly rest periods: Employees are entitled to a minimum daily rest of 11 consecutive hours and a weekly rest period of at least 24 uninterrupted hours. • Paid annual leave: Employees are entitled to a minimum of four weeks of paid annual leave. • Breaks: Employees have the right to adequate breaks during working hours, especially if their workday exceeds six hours.

EU member states have incorporated the requirements of Directive 2003/88/EC into their national labor codes. These regulations address key provisions such as maximum weekly working hours, rest periods, and minimum paid annual leave. Employers within the Union are required to comply with these laws to meet both national and EU standards.

Yes, the European Working Time Directive 2003/88/EC is mandatory in Luxembourg. As an EU member state, Luxembourg is required to align its national labor laws with this directive, which establishes minimum standards for working hours, rest periods, and annual leave to protect workers’ health and safety.

Send and receive faxes by email With our cloud PBX solution, send and receive faxes directly from your email account. If you have a fax machine, with an analog to IP converter, you can send faxes and receive them. However, the full transmission cannot be guaranteed for technological reasons detailed below. Is The Fax Dead – Read The Article ALTERNATIVE SOLUTIONS TO FAXES In most European countries, all telecommunication players have agreed to gradually replace the switched telephony technologies with ALL-IP ones by 2025. Today the use of a fax machine in a VoIP environment remains possible, but according to Règlement ILR dated 9th of August 2017, ‘‘there is no guarantee of end-to-end interoperability’’ (ILR/T17/9) As Voice over IP technology is optimized for voice transport, fax transmissions cannot be guaranteed anymore, by any operator. E-SIGNATURE In some cases, faxes have a legal value. This is why, the electronic signature is the best alternative at the moment. At Mixvoip, we developed our own module with an electronic signature. sign.mixvoip.com Customers can fill, sign and send their documents online. They have a legal value. The document will be also sent by email to the customer at the email address they provided.

Perform a Speed Test: We recommend starting by conducting a speed test on your line. Since the speed can never be guaranteed with a wireless connection (such as WiFi), please connect your computer to the router using an Ethernet cable. 1. Visit the Speed Test Website: Go to www.speedtest.lu and click on the"BEGIN TEST" button. Wait for the results to be fully displayed (PING, DOWNLOAD SPEED, UPLOAD SPEED). 2. Interpret the Results: YES: If the results match the speed of your Internet subscription, the speed issue does not seem to come from your line. Please check your computer hardware and settings. NO: If the results do not match the speed of your Internet subscription, please restart your router.(unplug the power from your router for a few seconds and then plug it back in)

An eSIM is the digital evolution of the traditional plastic SIM card. It’s software that lets you have a smooth installation by scanning a QR code only directly to your phone, enabling you to connect to local networks and even worldwide with ease. Convenient and eco-friendly, just scan the QR code, and you're all set!

Yes! eSIMs let you store several plans on your phone and switch between them instantly. Most devices allow up to two active eSIMs at once, though some may limit the number you can store (usually 8-10).

We recommend scanning the QR code and installing your eSIM right before your trip, while you are connected to Wi-Fi.

Newer Apple, Samsung, and Google smartphones likely support eSIM. For other devices, check if your phone is eSIM-ready. Models like iPhone 11, Samsung Fold S21, and Pixel 3 and later are compatible. If you are not sure verify on the manufacturer's website if needed.

When a call comes into your group, it rings your extension, which is then forwarded to your mobile. If your mobile has voicemail enabled, the call can be intercepted by your voicemail if it picks up before you do. Since the system can’t distinguish between a person answering and the voicemail picking up, the call is treated the same way. To prevent this, you can either disable your mobile voicemail completely or extend the voicemail delay to be longer than the group’s ring time. The best solution is to completely disable your mobile voicemail.

Voxbi Mobile is a fixed-mobile convergence app, so calls are forwarded to your mobile. A notification is typically sent before the call, but it's not always reliable due to the way phone's OS handle notifications. To reliably differentiate, you can use a dedicated eSIM for Voxbi calls. Two alternative options : 1. eSIM Icon 2. eSIM Ringtone

Mixvoip does not provide router access by default but grants full administrative rights for free upon request, allowing customers complete independence in managing their IT and internet security. For connections like copper DSL and coax, a modem might be necessary; however, the setup remains transparent. Customers may also configure their own devices using provided PPPOE credentials or fixed IP parameters depending on the connectivity service selected.

We would be happy to work with you! To find all the information about a partnership with Mixvoip, you can discover our page dedicated to this subject by clicking here.

The "monitoring and alerting" feature specifically tracks the real-time status of your network connectivity, sending alerts for any disruptions to ensure quick resolution. "Bandwidth graphs" visually represent the usage of your network's bandwidth over time, helping you monitor traffic patterns and manage network capacity effectively. Together, these tools are crucial for optimizing and maintaining reliable internet connectivity.

"Support hours" refer to the times customer service is available to help with general inquiries and support issues. "Fault processing hours" are specifically for technical teams to address and resolve service faults or disruptions, typically offering extended time slots to ensure you are never without internet.

Our Retail internet packages, tailored for the demands of retail business operations during weekends and peak periods like Christmas, offer extended support hours and quicker intervention times, available seven days a week. These are designed to ensure reliability during critical business times, unlike our standard fiber options which cater to general needs with more affordable pricing.

Yes, we offer highly redundant internet lines that enter the building through different paths. Many business premises can be connected via multiple routes, and we supply the fiber route maps, known as KMZ or KML files, for complete transparency. The internet lines can be set up to terminate on either separate routers or a single router. By using BGP (Border Gateway Protocol), we enable dynamic failover and manage redundancy effectively.

Businesses often require the same upload and download speeds due to applications like video conferencing, data backups, and large file transfers. A symmetrical setup, though potentially more costly, avoids bottlenecks and should be considered for businesses with more than 20 users. Investing in a symmetrical connection ensures efficient data handling, minimizes latency, and supports consistent performance.

The bandwidth on DIA (Dedicated Internet Access) lines is dedicated, not shared. These are point-to-point connections, meaning a specific portion of fiber is reserved exclusively for your use. Unlike shared technologies like X-GPON, DIA lines ensure consistent performance and reliable connectivity, as your bandwidth is not affected by other users.

Yes, upgrading your Emios Internet Line to a higher speed is easy. Just reach out to our sales team, and we can plan the upgrade without any intervention. Please note that in some scenarios, you might need to upgrade your router or choose a faster router from our managed router model to fully benefit from the increased speed.

Not all Emios Internet packages are fiber-based. Some buildings are not yet connected to the fiber network, and only DSL may be available, offering speeds below 100 Mbit/s. You can verify the available options for your address using our internet search page. The fiber network is expanding quickly, so availability may improve over time.

For selecting internet bandwidth, it's generally recommended to start with at least 1 Gbit/s, especially for businesses utilizing cloud services. If higher bandwidth is available at your location, opting for more can enhance productivity and prevent slow internet from impacting your operations. This recommendation applies both to large enterprises and SMEs, where the demand for bandwidth is consistently growing.

Mixvoip ensures each customer receives a unique, dynamically allocated IPv4 address by default, with no sharing of IP addresses or use of carrier-grade NAT. For a nominal fee, this can be upgraded to a fixed IPv4 address. We adhere to strict net neutrality, blocking no traffic to provide the purest internet experience. IPv6 blocks are also available at no extra cost.

While mobile connectivity over 5G or satellite may not match the reliability of fiber lines, it is comparable to or better than slow or poor-quality copper DSL connections. These options offer higher speeds and can be a reliable alternative in areas where traditional wired internet is not feasible.

Internet routers are often installed in locations with poor mobile connectivity, such as underground rooms, metal racks, or the interior of buildings. Modern building materials can also hinder mobile signals. To ensure optimal connectivity, we provide a separate mobile router that can be placed outdoors or in areas with better signal reception. This approach allows for reliable 5G connectivity where it is most effective.

The MTU (Maximum Transmission Unit) size for the 5G service is set to 1420 bytes. This is slightly less than the standard 1500 bytes.

There are two setups for the 5G backup activation: automatically, where our router detects an internet downtime on the primary line and switches to the 5G backup, or manually, by rerouting traffic on your firewall to the 5G router to initiate a failover.

The IP address assigned to your services will come from Mixvoip's own block of IPv4 and IPv6 addresses. Mixvoip handles the allocation of IP addresses, ensuring optimal performance and adherence to internet governance standards. Both static and dynamic options are available, depending on client needs.

Purchasing services directly from infrastructure providers often lacks the personalized service and customer support that Mixvoip offers. Beyond just providing connectivity, we add value with tailored solutions, expert support, and integrated services to meet specific business needs. In a business environment, comprehensive support for not only connectivity, but also network issues (including LAN and Wi-Fi), is crucial.

Installing our own cables isn’t feasible due to the enormous logistical, economic, and ecological challenges it would present. It's more practical and sustainable for local infrastructure providers to build and maintain these networks. This strategy prevents redundant infrastructure, which would be economically inefficient and ecologically unsound. Instead, by accessing these existing networks, Mixvoip focuses on delivering added value through our telecommunications services, ensuring customers receive high-quality, cost-effective solutions.

The 5G Backup service provided comes with unlimited data usage, ensuring continuous and unrestricted internet connectivity.
