TrunkPack Network Control Protocol (TPNCP)


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.

History


The TPNCP was developed to provide additional control and configuration capabilities over and above those offered by the standard control protocols.

Protocol dependencies

Wireshark


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

tpncp.dat

Preference Settings

Capture Filter


You cannot directly filter TPNCP protocol while capturing. However, if you know the UDP or TCP port used (see above), you can filter on that one.
