I have h323 working and it works perfect with the recommened versions of pwlib and oh323 By: Paul Cadach (pcadach) 2004-02-08 00:05:23.000-0600 It is chan_h323 related bug (found and fixed on my box) - when RTP structure cannot be created (don't let to know reason for it - say, low memory), it returns NULL value which is not analyzed in ast_h323.cpp... Two-line fix (immediately after "info = on_create_connection(GetCallReference());" line): if(!info) return NULL; By: Brian West (bkw918) 2004-02-14 23:09:38.000-0600 Attach a diff.
