Cisco Open Packet Telephony (OPT) provides the framework for delivering voice services over packet-based data, voice, and video networks. OPT encompasses a broad range of hardware platforms and Cisco software, delivering a continuum of voice solutions from core infrastructure to enhanced services over circuit and packet networks. The Cisco PGW 2200 (PSTN Gateway) is at the center of Cisco OPT solutions.
Provisioning a Cisco PGW 2200 is the process of preparing it to communicate with an SS7 network, with Cisco media gateways, and with the other components of an OPT solution. The Cisco Voice Services Provisioning Tool (VSPT) provides an easy-to-use graphical tool to provision Cisco PGW 2200.
