I have it core dump on me with latest cvs,
at chan_h323.c:1164->connection_made ->         if (!p->owner)

I beleive this is a race condition on the the channel, since the struc 'p'
is valid
but the channel appears to have vanished right after 'find_call'

do a back trace on the core file when it dumps, compare is to this
