[Asterisk-Users] chan_h323 Ringing Congestion causes * segfault

[Elliott]

We have an odd problem, where inbound H323 (chan_h323) calls will sometimes 
cause a Ringing Congestion that appears to keep the channels open and never 
release it until we kill and restart asterisk. These "Ringing Congestions" 
start to pile up, which eventually crashes Asterisk.

H323 Gateway -> Asterisk (chan_h323) -> Tor2/PRI -> PSTN

Has anyone ran into this problem or know how to resolve it? The H323 device 
making the calls doesn't seem to have a problem calling other H323 gateways 
or gatekeepers, this problem only appears in Asterisk.

Again this problem is intermittent and occurs once a day.

I have included a paste of the "Ringing Congestions" below as well as the 
GDB dump.

Thanks
