What are SIP, SIP trunk and SIP trunking?
SIP (Session Initiation Protocol) is a data transport protocol for Unified Communications (UC). SIP trunk is an IP link between your telephone exchange (Call Connect, Forum) or collaboration platform (Microsoft Teams, Cisco Webex, Genesys Cloud CX, ...) and the public telephone network, to exchange your communications via the SIP protocol. The SIP trunk is sized by the number of voice channels or simultaneous communications.
SIP trunking is the optimized method for sharing a line with multiple users to exchange your Unified Communications over the Internet or your IP MPLS private network (Explore).
Proximus VoIP services are available on site and in the cloud
Phone Line Enterprise is the VoIP service with a single communication channel and a single number. Enterprise Voice and Business Trunking are the VoIP services provided in the form of a SIP trunk in which several voice channels are associated with several numbers, thus supporting several simultaneous communications on the same access line.

Michel Derycke, ICT Project Manager at Ajinomoto Omnichem
If we're interested in capitalizing even more on e-commerce prospects, I think that a faster connection will also benefit customers.
Eric Wieme, IT and Network Manager
The work will become more fluid and it will be easier to reach us. The speed of the connection will make it easier to intervene. There will be new benefits for the public too with new services.
Richard Mikut, IT Development Manager at the intermunicipal environmental management company Hygea
First of all, we work with VoIP, so all our telephony runs through the new line. That means that a fast and stable connection is very useful.
Rik Walraevens, co-owner Schevenels Project Interieurs
Prisons are going digital
VoIP will be available in the cells so that prisoners no longer have to make calls in the corridor; and digital television is also underway. In time, that digital device will evolve into a service platform, for purchasing products from the canteen, ordering a film or borrowing a book, among other things.
