From Telephony to IP

We constantly work to improve and upgrade our network

"Ready for the future with Voice over IP technology

The way we communicate in our business environment has evolved completely. This can call for a renewal of the IT and network infrastructure. More and more companies indeed choose to integrate enterprise communications on an IP platform. For end users this transition offers nothing but benefits"

Network modernization

White paper

This white paper outlines the history of the communication network

"Previously the network was used solely for the transfer of voice. Since the advent of the computer in the seventies, network capacity is also needed to transfer data. The need for data transmission capacity increased with the evolution of computers, operating systems and applications. The traditional copper technologies no longer suffice and make place for a fiber network with an all IP platform."

Frequently asked questions

All you need to know about Network modernization and migrations towards IP

Why is Proximus modernizing its network?
  • Proximus constantly works to improve, optimize and upgrade its network. In 2016 we will change, update and migrate various services on our IP network, from massive optical fiber roll-outs and ADSL client upgrades to faster VDSL & VDSL2 and the phasing out of older technologies.
  • This ties in with our "Move to all IP" transformation project, driven by three main factors:
    • Customer satisfaction: Our absolute priority is to deliver the “Best Network Experience” to all our customers, both in terms of fixed and mobile connectivity and data and voice.
    • Market evolution: IT applications are evolving. Not only is the quantity of data travelling over networks rising exponentially year over year, but the quantity of “connected” devices, sensors and objects (IOT) is also increasing at a rapid pace. Proximus is thus compelled to follow suit and have its network evolve to be future-proof.
    • Evolution of technology providers: Global manufacturers of network components and communication equipment (call controls and telephone exchanges for instance) are evolving towards IP technology, gradually phasing out analog and digital connectivity equipment.
What does the migration to VoIP mean for my alarm system, modem applications, lift phone and fax communication?

Alarm systems
If you have a security system that transmits alarms over the fixed telephone network and you consider switching to VoIP, we recommend to ask your security provider if the security system is compatible with VoIP.

If it is not compatible, we can provide you with the Bizz IP Box, an adapter that converts the IP signal to an analog signal, which solves the compatibility issue.

Note that IP telephony components (modem, Bizz IP Box, PABX) must be powered. This means that if the service needs to work during a power outage all elements should be backed-up with a battery (UPS).

Modem applications
Applications that communicate over the traditional fixed network via a modem are affected by the switch to IP.  This might include: ticketing machines, payment terminals, ATM machines, building services, machine-2-machine, remote management, etc.

Lift phones
If you switch to IP, only lift phones that currently transmit emergency calls over the traditional fixed network are affected. We recommend you to contact your lift manufacturer to see which necessary steps you need to take to ensure the reliable operation of your lift phone

Fax communication
When switching to VoIP, there are many options to continue using your existing fax machines and numbers, without having to worry about downtime or missing messages.

We advise to migrate your fax numbers to a web-based fax service. This means you will no longer need a traditional fax machine, but instead you will send and receive fax messages on your computer using the internet.

Is Proximus stopping support on ISDN2 (basic access) voice access and forcing customers that currently use ISDN2 to migrate to Voice over IP technology?

Not at all; from 1 January 2017 Proximus will merely be integrating existing ISDN voice access on the VoIP network. Support of customers with ISDN2 (basic access) lines will continue to be ensured.

For customers that subscribe to Proximus voice services after January 2017, this implies that they will be able to order VoIP lines or ISDN30 on PRA.
