The P32mxi system can convert analog voice channels to Voice over IP (VoIP) packets using the Media Gateway Control Protocol (MGCP).
In the Line Provisioning window, Configure one of the voice channel cards. Check the Use Packetized Voice box for the channel you want converted to VoIP and press the Packet Voice Options button to bring up the configuration window:
The CID # at the top of the configuration window indicates the physical channel number (on the Amphenol connector) of this voice channel. To enable VoIP conversion, click the Voice over IP button as the transport type. You can explicitly enable an IP address for this channel if you want.
Voice compression is negotiated between the P32mxi and the end terminal. To allow certain types of voice compression, check the boxes for the compression algorithms you want to allow to be used. You can also Enable Echo Cancellation and Enable Voice Activity Detection. It is highly recommended that you leave both of these options enabled.
