SIP trunking is a flexible and dynamic functionality that can be extended to any number of applications.

  • Cheaper more reliable IP connectivity
  • Free internal calls

SIP is a reliable and cost effective way…


…of allowing your phone system to access the outside world via a broadband or data connection to our network.

 


SIP enables you to have a PBX installed to use Voice-over-IP (VoIP)…


…even to outside the enterprise network by using the same connection as the Internet connection. A single trunk includes multiple voice sessions.

  • More specific Quality of Service: (QoS) measures to ensure better and calculated voice quality
  • More reliable: than the traditional PSTN as a number of failover solutions can be implemented
  • Take your telephone number: with you wherever you move
  • Receive any UK number: at any site in the UK.
