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.
