Summary:                    [patch] Segmentation fault with unanswered inbound
call via chan_ooh323
Description: 
If i configure a sip phone to hangup a call after 30 seconds of ring time
from a inbound call, the chan_ooh323 module crash and asterisk segfault...
tested using grandstream gxw-4024 gateway and linksys spa921 phone.

attached 4 logs:

the phone is configured to hangup after 60 seconds:
1-ooh323-normal-hangup.txt
2-asterisk-normal-hangup.txt

the phone is configured to hangup after 30 seconds:
3-ooh323-crash-hangup.txt
4-asterisk-crash-hangup.txt

asterisk seem to crash only when the cause of hangup is:
22:01:35:395  Cleaning Call (incoming, ooh323c_2)-
reason:OO_REASON_LOCAL_CONGESTED

if the cause of hangup is the following, asterisk doesn't crash:
21:57:45:129  Cleaning Call (incoming, ooh323c_1)-
reason:OO_REASON_REMOTE_CLEARED

so, if the phone doesn't hangup the call before 60 seconds of ring time,
asterisk doesn't crash.

actual work around: configure all phones to hangup after 60 secs of rings

outgoing calls doesn't have any problems.
