It usually means there was a timeout reading TPKT
header. TPKT is a wrapper
around a H.245 message. It consists of 4 bytes: a
constant value 3, a padding byte (usually 0),
and 2 bytes showing packet length. Maybe your
equipment does not set the first byte to 3?
A tcpdump/wireshark could reveal more
details.

Openh323gk-users Digest, Vol 22, Issue 16
Hi,
we have been having an issue with a Tandberg Edge 95
MXP that is failing to establish calls via our gnugk 2.2.7.
Tandberg Edge 95 MXP (Malaysia) ---
gnugk227 (Australia) --- Tandberg 150 (Australia)
The gnugk227 is in routed mode and proxies all calls.
Both the Edge 95 and T150 are registered to the gnugk227.
The T150 initiated the call via the gnugk227 to Edge
95. The usual arq, acf, q931 (setup, alert, connect) happens until the call
connection failed in the exchange of h245 terminalCapabilitySet.
Please see the gnugk log below:

Syslog on the edge95 showed that the
edge95 did receive and respond to the request for terminalCapabilitySet from
the gnugk227.
We have had many
calls by Tandberg endpoints via the gnugk227 without problem except for this
particular model, Edge 95 MXP.
Any
idea what could be cause of the Timeout and NOT TPKT PACKET?
Thanks in advance for all help.
Cheers,
Paul
