About H.264 plugin - actualy I have 3rd party static library for H.264 encoding/decoding and use H264 plugin as wrapper to connect library to h323plus. I don't think anyone has interest of half working plugin without static library...

The problem is caused by an master/slave conflict when first opening the audio channel which results in the OLC beingšrejected. The correct processšis to renegotiate the OLC. It appears that the T1000 cannot properly renegotiate the OLC and incorrectlyšallocates an invalidšsessionID of 0 which causes the assert and behavioršyou highlighted.
š
I also see you are using a modifiedšand working H.264 plugin and have decided not to contribute any of that workšback to the project. This is a pity.

Sending log.
T1000 in most cases after Reject sends OLC with sessionID=0, and in less cases send OLC with sessionID from 32 up to 53 (increase 1 after each reject).

Session ID should never be zero. This is clearly an error coming from the T1000 unit.

Can you post a level 6 trace showing the condition the T1000 sends an OLC with sessionID = 0

Hi.

I have problem when I reject OpenLogicalChannel (audio) while communicating with Tandberg T1000.
In most cases Tandberg send me OpenLogicalChannel again with sessionID=0 so my application falls in assertion
in file rtp.cxx line 760 :
PAssert(id > 0 && id < 256, PInvalidParameter);

I could not find valid value range for sessionID, but I don't like when application crashes in this case :(
What can I do in this situation?
