TPNCP is Audiocodes' proprietary network-based protocol. Using this method, the VoPLib (AudioCodes’ Voice over Packet Library is a proprietary, all-sources-included API library, enabling control of all VoP-related functions of devices in AudioCodes’ TrunkPack-VoP series) communicates with the device via the IP network.
The TPNCP was developed to provide additional control and configuration capabilities over and above those offered by the standard control protocols.
TPNCP over UDP.
TPNCP over TCP.
The TPNCP dissector is fully functional. The TPNCP protocol is constantly changing and requires tpncp.dat file for proper registration and dissection. The tpncp.dat file resides in TPNCP folder in Wireshark program directory and it is read at program start. The tpncp.dat file is distributed with Audiocodes' SW Release Package. The example of tpncp.dat file
