Server 2x XEON quad core and 4g DDR crashes on 110-120 simm. H323 calls.

NOTE: this is one case. We do not notice same behavior on other servers which runs up to 250 sim. calls for several hours straight.

No Audio.

h323 set debug shows:

   RTP channel id 1 parameters:
   -- remoteIpAddress: 127.0.0.1

binaddr in /etc/asterisk/h323.conf has bad values.
