SIP Trunking is generally used to describe connectivity between a SIP enabled PBX or SIP enabled dialer and the carrier using Session Initiation Protocol (SIP). Most recent versions of popular PBX equipment including Avaya, Cisco and Nortel and predictive dialer equipment such as Aspect, Altitude, Asterisk, Vicidial and Interactive Intelligence, just to name a few, natively support SIP Trunking.
Star Telecom provides SIP Trunking services for Canada, USA, UK, Australia and internationally.
