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--

I make some tries to locate segfault, but have no much soccess. I've
discovered that sometime (not regular) dev name in channel structure became
NULL. I seems to be some kind of memory corruption.

At first part: i think that it is real inband message. I think, that
really provider sends inband ringing, even if I reject the call. Is it
really strange? Can I read some document about right behavior? In fact I am
working in that provider and therefore can get more information.

May be we can add some configuration option for this situation or dialplan
variable to control chan_misdn?
