VoIP/SiP Banner

VoIP or SiP telephones look very similar to normal telephones, but they connect to the data network rather than to a standard PSTN line. Voice calls are converted to data and carried over the internet, rather than over traditional copper wires. VoIP, or Voice Over Internet Protocol is a general term for routing voice calls over the internet, where as SiP (Session Initiation Protocol) is an open standard protocol that has become a standard for the majority of unified Communications equipment manufacturers.

At Handset Solutions we stock a range SiP enabled handsets from a multitude of manufacturers, including Snom, Yealink, Polycom, Cisco and Grandstream, ensuring whatever your requirement we will have the perfect SiP handsets for you.
