What is SIP Trunking?

In essence, a cost effective replacement for your ISDN lines, connecting your PBX to the public network over the Internet. You can choose to have SIP Trunking - Elite Voice Connect only or alongside IDSN to give you a truly resilient communications package. 

Reduced Call Costs

Reduced Call Costs
SIP trunks can deliver cheaper national and international calls as they are carried out over the IP network rather than the PSTN (Public Switched Telephone Network).

Free UK calls & Fraud Protection

Free UK calls & Fraud Protection
Our SIP trunking service provides free call termination to UK fixed destinations, including 01, 02 and 03 number ranges, allowing you to focus on the service benefits rather than a straight pricing discussion.


Having a trusted CLI and dedicated IP address ensures that no unauthorised calls can be made via your SIP trunks. As Elite monitors your virtual lines, you can guarantee that any unusual activity will be dealt with as quickly as possible.

Once the SIP trunks are activated, it’s easy to scale up and down as you please – the perfect solution for fast growing or seasonal businesses.

True Resiliency & Business Continuity

True Resiliency & Business Continuity
Elite Voice Connect SIP traffic is controlled from a central location, which means calls can be automatically diverted should disaster strike. SIP also allows for business integration for video applications, Computer/Telephony Integration (CTI) and Instant Messenger services like Google + and Microsoft Lync. SIP trunking can act as a voice solution and a disaster recovery solution in one.


SIP lines are much easier to operate, maintain and upgrade. Controlled centrally, if a disaster occurs or staff are unable to make it into work, calls can be diverted at the click of a button. Combining voice, fax and data into a single, unified infrastructure also makes your communications portfolio much easier to manage and is the the next logical step in the advancement of business communications.
