SLA
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.
Publish
SLA
Internet packages differ not only in speed but also in the level of service guarantees (SLAs). A higher-tier SLA may cost more, but it provides faster response times and dedicated support. This is particularly important in industries like healthcare, finance, or retail, where internet downtime can cause financial losses, compliance issues, or even safety risks. Investing in a strong SLA protects your business continuity and ensures operations run smoothly in all situations.
Publish
SLA
"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.
Publish
SLA
Although support for telephony, local network, and Wi-Fi is not included in our retail internet packages, we offer specialized packages for the 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.
Publish
SLA
Our Retail internet packages meet 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.
Publish
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.
Publish
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.
Publish
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.
Publish
The installation cost depends on how accessible and roof-ready your location is.
If your roof is easy to reach and everything is prepared, Mixvoip can handle the setup directly: typically from around €150 (for customer-prepared sites where Mixvoip assists with configuration, testing, and consulting).
For more complex rooftop installations requiring professional mounting, waterproof sealing, and cabling, we may need to outsource the work after a site survey or detailed photos. In those cases, total costs can reach up to €2,000, depending on structure and access.

Satellite connectivity requires a clear, unobstructed view of the sky. The antenna must be placed outdoors, ideally on a rooftop or another elevated location free from trees, walls, or other obstacles. It cannot be installed indoors (such as behind a window or under a roof overhang), as this would block the satellite signal.
In most installations, the antenna is mounted on the roof, with a single PoE-powered Ethernet cable running down to the indoor router.
Mixvoip’s team will assist with configuration, positioning advice, and testing to ensure you get the best possible signal quality. However, we’re not certified rooftop climbers, so for rooftop access or complex mounting, we recommend using a qualified local installer for the physical installation.

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.

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.
Publish
Yes, upgrading your internet line to a higher speed is in most cases 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.
Publish
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 Wi-Fi), 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 or network.
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.

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.
Publish
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.
Publish
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.
Publish
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 30 users. Investing in a symmetrical connection ensures efficient data handling, minimizes latency, and supports consistent performance.
Publish
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.
Publish
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.
Publish
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.
Publish
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 the raw cable infrastructure. This strategy is economically efficient and ecologically sound. By accessing these existing networks, Mixvoip focuses on delivering added value through our telecommunications services, ensuring customers receive high-quality, cost-effective solutions.
Publish
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, support for not only connectivity, but also network issues (including LAN and Wi-Fi), is crucial.

On some phones, like Xiaomi devices, calls may appear as "anonymous" when VoLTE is enabled, even if the caller's number is valid. This happens because the phone uses a different method to read the caller ID, and this information is not always transmitted by the network. Recommended solution is to disable VoLTE on your device. Incoming calls should then display the caller's number correctly.

Absolutely. Voxbi uses secure protocols to sync contacts and never shares your data without permission. You control which contacts are private and which are shared with the team.
Publish
To enable contact synchronization, make sure your contacts are not marked as Private in Voxbi Web, Voxbi for Windows, or on my.mixvoip.
By default, contacts created from Voxbi Web or Voxbi for Windows are marked as private. To make them accessible across your devices and shared within your PBX environment, you need to manually uncheck the Private option.
On Voxbi Mobile:
All public PBX contacts are instantly available under PBX Contacts
To sync your personal phone contacts, you must grant the Voxbi app access to your device contacts
Once permission is granted, newly added phone contacts will automatically appear in the Local Contacts section of Voxbi Mobile

When a call comes into your group, it rings your extension and is then forwarded to your mobile. If your mobile voicemail is enabled, it may intercept the call if it picks up before you do. Since the system cannot differentiate between a person answering and the voicemail picking up, the call is treated the same way. The most effective solution is to disable your mobile voicemail completely.

The difference is based on the type of network used to carry the call.
SIP (purple button / VoIP) calls use your data connection (Wi-Fi, 4G, 5G, etc.). Their purpose is to route calls through the internet, allowing you to use your business telephony system and its features.
GSM (green button) calls use your mobile network (SIM card) instead of data. Their purpose is to place calls through your mobile carrier, like a traditional phone call.
In short, VoIP uses data, while GSM uses the mobile network to handle the call.
