Session Initiation Protocol or SIP, is a communication protocol that facilitates openness, connectivity, simplicity, choice and personalisation. It is a standard that has been developed by the same standards body that were behind the Internet Protocol (IP).
Its simplicity, power and extensibility has led to SIP’s rapid adoption for other uses across the internet notably for use with Voice over IP and for Instant Messaging.
The benefits offered by VoIP as a way to merge voice and data networks, reducing costs and opening up new and powerful applications has been given a new degree of scalability and interoperability, thanks to SIP.
SIP trunks can cost £6 per month compared to £10-£20 for a BT line and SIP trunks also, usually, include FREE local, national and calls to mobiles (fair usage applies).
Most modern phone systems are SIP compatible so can connect to SIP trunks without extra hardware or upgrades as is the case with older phone systems.
