| Description: | This issue is reproducable in the following way:
Call comes in on ISDN (CAPI) channel, Asterisk connects to SIP (going via MS Lync to Exchange 2010 UM). UM server tries to forward call to another extension on ISDN (Alcatel PABX). Lync sends SIP INVITE to Asterisk, ISDN line starts ringing. If I then hang up incoming call (ISDN->*sk->Lync), the Lync->*sk->ISDN call doesn't stop ringing. When call is answered, Asterisk crashes: {noformat} [2013-05-10 09:24:53] ERROR[5502]: astobj2.c:115 INTERNAL_OBJ: user_data is NULL lemonade*CLI> Disconnected from Asterisk server [root@lemonade asterisk]# /usr/sbin/safe_asterisk: line 145: 5485 Segmentation fault (core dumped) nice -n $PRIORITY ${ASTSBINDIR}/asterisk -f ${CLIARGS} ${ASTARGS} > /dev/${TTY} 2>&1 < /dev/${TTY} Asterisk ended with exit status 139 {noformat} Full SIP debug will be attached | ||
