Offering many benefits over traditional telephone lines, SIP Trunks are now being widely adopted as a way of delivering voice and cloud based services to businesses in a more flexible and cost effective manner.

With SIP intelligent devices communicate directly with each other over a simple transport infrastructure. This contrasts with the traditional telephone network, where transport between dumb endpoints is provided through an intelligent network core. This difference allows the network to become a commodity and allows any device attached to the network to provide a service to any other.
