What is SIP Trunking?

Session Initiation Protocol (SIP) Trunking is a service that uses the protocol to provision voice over IP (VoIP) connectivity between an on-premises phone system, and the public switched telephone network (PSTN). SIP Trunks offer a more flexible and lower-cost alternative to ISDN for inbound and outbound voice calls.

For added reassurance when switching to us, you can even use SIP Trunking with existing ISDN connections to ensure the transition goes smoothly. Having a robust disaster recovery plan and backup facilities in place can be crucial.

SIP Trunking is more secure
