Summary:                    Crash after attended transfer and call park
Description: 
Hi all,

I found a crash case after attend transfer and call-park usages.

Here is my scenario:
Phone 1: 1001
Phone 2: 1002
Phone 3: 1003

Step 1: 1001 calls 1002, and 1002 answers the call.
Step 2: 1001 makes an attended transfer to 1003, and 1003 answers the
call.
Step 3: 1001 hangups the call with 1003, and then 1002 communicates with
1003.
Step 4: 1002 makes a call-park to Asterisk. After Asterisk repeats the
parking lot numbers to 1002, Asterisk disconnects the call with 1003
strangely.
Step 5: 1001 calls 1002 once again, and Asterisk crashes.

I verified the case on 1.4.22 and 1.4.20, and the crash situation happened
on both versions. I doubt that Asterisk did not handle transferee well, and
if transferee wants to do call transfer or call park, it would fail.

I am sorry for my mistakes. I changed my dial-plan with different extension
numbers. EXT 1002 is the EXT 1006 in my dial-plan, and EXT 1003 is the EXT
1007 in my dial-plan. And the issue is indeed not a SIP transfer issue and
should be placed in feature category. 

In order to debug the issue, I dump the gdb back traces as attachment.
Thank you.
