SIP Trunking is a form of VoIP (Voice over Internet Protocol) telephony that provides a voice connection using data rather than a fixed line. It uses Session Initiation Protocol (SIP), a signalling protocol which packages voice into data packets, enabling them to be sent via the internet to a SIP Trunking provider’s IP calling network and then out to the Public Switched Telephone Network (PSTN).
It is a replacement solution for the traditional ISDN lines that transmit data and voice digitally, over physically wired connections. Although, most VoIP services boast an ideal ISDN replacement, SIP Trunking allows you to make and receive calls using IP technology without needing to completely replace your PBX, making it the perfect solution for businesses who aren’t yet ready to move to a fully hosted system. This may be because they do not want to replace their on-premise PBX or they do not want to re-invest in new telephony equipment.
