What is SIP Trunking?
AMA SIP Trunking Service unifies voice, data and Internet services over an IP connection, leveraging your existing IP PBX. It’s an ideal converged solution for a single location business with 10 or more phone lines.
Based on the Session Initiation Protocol, a SIP trunk provides the connection between your network and the public switched telephone network (PTSN). With this SIP trunk connection, you can make phone calls from your IP PBX device without additional physical wiring, thereby reducing the recurring costs of separate voice and data circuits and the costs associated with the purchase, support and maintenance of media gateways.
Integrated access combines your voice and data onto a common access circuit, enabling you to achieve greater economies of scale and simplify the management and maintenance of your communications infrastructure.
