Hi,
I'm working on H.239 implementation and find out that devices might ask SessionID=0 for a new video channel. In particular I did a test with Mirial. I was checking the thread http://lists.packetizer.com/pipermail/h323plus/2009-December/001269.html and it's mentioned that the SessionID=0 is invalid. I know it's not following the standard as for RTPSession the range is from 1..255, but for compatibility, don't you think we should allow it? I did a test call from Mirial to Tandberg and Tandberg didn't have a problem with it. The lines involved are rtp.cxx from PAssert(id > 0 && id < 256, PInvalidParameter); to PAssert(id >= 0 && id < 256, PInvalidParameter); and h323.cxx // We must have a valid sessionID if (sessionID < 1 || sessionID > 255) to if (sessionID < 0 || sessionID > 255)
Thanks,
Marek
