Recently I patched Asterisk 1.4.16/1.4.16.2/1.4.17 using www.b2bua.org codec negotiation patch. I tried on all versions.
After that when I make call from SIP endpoint to H323 network using chan_h323 driver Asterisk automatically crash.
I don’t know what problem happen with Asterisk.
Below is backtrace:
