Simplify and evolve your voice network

Many organizations today are seeking the most cost-effective and flexible way to transition to IP-based services. One highly-effective strategy is SIP (session initiation protocol) trunking.

SIP trunking acts as a gateway to future network-based, productivity-enhancing applications by integrating voice capabilities with unified communications (UC) tools.

With SIP trunking, you can enjoy the productivity, efficiency and customer service benefits of UC, while reducing disruption and infrastructure investment costs.

How SIP trunking works

SIP Trunking service from Bell provides organizations with a gateway to the public switched telephone network (PSTN) through an IP network. This allows voice calls – whether local or long distance – to run over a single data backbone.

Not only does SIP trunking provide more flexibility and simplicity in managing your network, it also provides the foundation for the deployment of on-premise or network-based UC applications, while offering a strong return on your IP technology investments.

SIP Trunking service from Bell is delivered over a mature and proven VoIP infrastructure and top-rated North American MPLS/optical foundation on which Bell flagship IP VPN and Ethernet services are based.
