SIP Trunking

Voice services with increased quality and reduced cost



SIP trunking offers businesses a more flexible, resilient, scalable and cost efficient way to connect PBXs to the voice network compared to using ISDN. Exponential-e’s SIP trunking service does more than just provide basic voice. Using our advanced Voice Services Platform and resilient core Network we provide high quality voice calls and additional resilience, load balancing, call queuing and disaster recovery features.

What is SIP Trunking

SIP stands for Session Initiation Protocol (SIP) which is a signalling communications protocol, widely used for controlling multimedia communication sessions such as Voice and video calls over Internet Protocol (IP) Networks.

SIP is supported by a wide range of PBXs and is an alternative to traditional ISDN links

SIP Trunking is Exponential-e's product to offer SIP Connectivity to businesses with PBXs, and builds on Exponential-e's resilient and secure core Network.

Business Benefits

Disaster Recovery and Business Continuity
  • What happens if your office is affected by flood or fire?
  • If you have ISDN connections it can take some time to reroute calls during which time your business is disrupted. With Exponential-e’s SIP trunks calls can be instantly rerouted by alternative destinations selected by you. This can be to another office or several locations based on the destination department (e.g. sales, service). SIP Trunks are therefore a powerful business continuity tool.

Don't just take our word for it…

I approached Exponential-e because we had just been told by our existing ISDN provider that they would not be able to get our ISDN30 installation in on time for our office go live date. Exponential-e helped by offering a resilient SIP solution that they guaranteed would be installed in time and within budget. The result was that they met the deadline date and were very helpful in every aspect of the installation process and offered excellent support and service after the installation of the SIP circuits. I would recommend Exponential-e to people who need a top notch service provider for any type of comms circuit installation and would not hesitate in using their service again.
