Summary:                    mISDN don't make hangup and crash
Description: 
Yesterday I have notice some bad situation. When calling from SIP to cell
phone, over chan_misdn and hangup on cell phone without take a call. On sip
phone I still hear ringing and call hangup only after time-limit specified
in Dial.

Here is step by step:
We call to cell phone:
--misdn-begin.txt--

We make hangup on cell phone. But still hear ringing on SIP:
--misdn-hangup.txt--

Finaly we hear hangup on SIP and saw fallowing in console:
--misdn-end.txt--

Also after 5-6 tries of such calls asterisk crashed:
--misdn-crash.txt--
--core-1.txt--
--core-2.txt--

Looks like I really hear some fake ringing, maybe from my phone (SPA 941).
I try to test more and report. Still have question about crash. I have one
more now. It is very similar:

Asterisk crash when I have troubles with ISDN and can't make or receive
calls. I call several times and have a crash. All this crashes caused on
unsuccessful calls by wrong dev pointer. Where it can be corrupted?
