Problems with H245NegLogicalChannel::HandleOpen freezing my device

Hi,

If my experience with the D-Link i2eye and your report are anything to go by,
D-Link devices are nothing to brag home about.

So, DVC-1000 gets a cold when receiving an Open reply?
This is most surprising, and I would expect that it comes from some particular
bit inside that PDU rather than the PDU as a whole.

Did you try to call without video?
Did you try to call with NetMeeting (or another H.323 endpoint not from
OpenH323)?

I suggest that you isolate the offending bits, rather than discarding the PDU
completely.

If this DVC-1000 is accessible from the outside, please feel free to contact me
off-list.

Regards,
Guilhem.
