SIP Trunks and VoIP Lines

Session Initiation Protocol (SIP) was created to enable voice connection to be established over a computer network. It has now been established as the industry standard for delivering phone lines via a data connection. A phone line that is delivered to you via a data connection using SIP protocol is called a SIP Trunk.

SIP trunks deliver outstanding savings compared to a traditional landline plus internet connection set up.

Vadacom are experts in SIP Trunking integration for business – we were New Zealand's first SIP Trunk integrator.
