SIP Trunking

VoIP calls are made up of two components – the call signalling and the call media. In other words, in order for one phone  to  connect to another phone, we need a way to set this up using telephone numbers - and then make voice crisscross between the handsets.

There are a couple of standards for VoIP,  initiallyH323 and now SIP.  A SIP Trunk is a logical connection between two endpoints, such as a phone system (PBX) and a Service provider (such as VoIP.co.uk). The word “Trunk” is used in telecoms to mean more than one – so a SIP Trunk can typically carry more that one phone call, however it is possible to connect a single SIP telephone directly to VoIP.co.uk without using a PBX

VoIP.co.uk offers more than just a simple SIP trunk. In fact, multiple trunks can be configured on our user portal, connecting multiple sites together.  VoIP.co.uk’s call routing engine brings lots of of advantages, for example a multi-site organisation can benfit  from call load-sharing between sites, thus improving their call handling rate, or the network can be set to divert calls automatically in a disaster situation. Teleworkers with IP telephones or softphones can enjoy a direct connection to VoIP.co.uk and connect back to theiroffice when required. If requested, VoIP.co.uk supports full SIP and media encryption for customers needing ultimate security of their calls.
