[Asterisk-Users] Sangoma Card Question

[Rich Adamson]

There is always a delay associated with the pstn line hangup, asterisk 
sensing the hangup (which is really a delay in the Central Office), and 
asterisk sending the sip packet to the sip phone indicating the call was 
hung up. Not unusual for a sip phone to ring one or two times after the 
pstn caller hung up. Whether its one ring or two rings is 100% dependent 
on how quickly the Central Office disconnects the line. In my case, the 
disconnect arrives about 5 to 8 seconds after a pstn caller hangs up.

Based only on your description of events, I would doubt the above issue 
has anything to do with the issue you described in earlier posts.

To help understand what might be happening, I'd suggest inserting some 
NoOp dialplan statements to see if you can track down the original 
hangup issues.  If you're using an 'exten => h, ' statement, try 
inserting a step something like 'exten => h,1,NoOp,"step one"' to help 
detect whether this is a dialplan issue.
