[asterisk-users] Stuck Parked Calls?

[Jonathan C. Bailey]

I've lurked for a while, but I think this is one of my first "pleas" for help. I'm having issues where a parked call using the macro below is getting "stuck". Users park the call via a blfxfer key on an Aastra phone. If the call is a blind transfer, it tries to park the call. If it isn't a blind transfer, it tries to unpark the call. Only 2 extensions (2759 and 2760) are doing the parking. The other extensions only pick up calls (by dialing the 3 digit park code. The phone shows as in use and there is a call that I see via "core show channels". I can't seem to soft hangup the stuck channel either. Only killing Asterisk forcefully will solve the issue. We're running Asterisk 1.4.18.

Thanks for any help!
