Frequently Asked Questions

SIP trunking is a form of telephony that connects your business to the Public Telephone Network (PSTN) using a data circuit and Voice over IP (VoIP), rather than traditional BT analogue or ISDN lines.

Business SIP Trunking is now the standard for any business needing voice calls. With one-off and monthly rental costs being up to 60% lower than ISDN, businesses can stop spending high amounts on telephone lines. Call charges are also currently increasing on ISDN but decreasing with SIP meaning even more money can be saved.

Most businesses cannot afford any downtime. With our SIP Trunks there are multiple failover and resiliency options which can be deployed depending on individual customer requirements, providing unrivalled business continuity.

SIP (Session Initiation Protocol) is the industry standard method for controlling Voice over IP (VoIP) calls and is used by a wide range of operators to provide business SIP trunking and Hosted Telephony services.

SIP is the protocol used to control the call itself, including initiating and terminating the call. The actual call media is then transmitted using Real Time Protocol (RTP).

SIP trunking therefore allows business grade phone calls to be made over voice ready data circuits.
