|Description:||Incorrect parsing in sip_subscribe_mwi was crashing Asterisk.|
In sip.conf, just below your "register =>" lines and before peer/user definitions, try adding:
mwi => 1234@other_host/1234
...then issue "sip reload" - should crash.
Partial gdb backtrace:
#0 0x00007fa68aabb990 in strchr () from /lib/libc.so.6
#1 0x00007fa65c0d4af7 in sip_subscribe_mwi (value=0x0, lineno=0) at chan_sip.c:7594
Attached patch corrects the problem.

Re-opened because patch in this bug contains support for TCP MWI subscriptions as well as the fix covered by the related bug.

I do have exactly the same issue in Asterisk 184.108.40.206-rc1 and 10.2.0-rc2.
I cannot supply a backtrace because it's embedded system.
