Abstract:
1. A system to test voice quality over call path on a packet-based network, comprising: a first voice quality tester (VQT); a second VQT communicating with the first VQT via the call path; a first call signaling stack to establish a call signaling path between the first and second VQTs according to a first call signaling protocol; and a second call signaling stack to establish the call signaling path between the first and second VQTs according to a second call signaling protocol, either the first or the second call signaling stack being selected by a user to establish the call signaling path, wherein the first VQT comprises: a VQT application to generate control and data information; a dynamic link library (DLL) to relay the information; and a Media Over Packet Interface (MOPI) to receive the relayed information from the DLL, wherein the VQT application includes a graphical user interface (GUI), including a port setup screen, the user selecting the selected call signaling stack at the port setup screen, wherein the relayed information received by the MOPI includes a command which is specific to the selected call signaling stack, and the MOPI transfers the command to the selected call signaling stack.
