Summary:                    Peer does not hang up when caller hangup while
app_dial is executing - Deadagi
Description: 
I am trying to execute a dead agi application:

exten => 1111,1,DeadAgi,calling.pl
exten => 1111,n,Hangup()

in calling.pl I have:
$result=$AGI->exec("Background", "connecting");
$dialstr = $type."/$callednumber@".$providerip."|90|rHL(" . ($calltime *
60 * 1000) . ")";
$result=$AGI->exec("DIAL $dialstr");

everything works fine if the caller does not hangup and the progress tone
is played to the caller but if the caller disconnect the call while
connecting.gsm is played, the peer does not disconnect even after the
originating channel is hung up.
Should * not disconnect the briged channel when originating channel
dissconnects?
Asterisk reports the caller disconnect and DIALSTATUS is CANCEL but the
bridged call stays in progress and connects unless a restart is issued. If
this is normal (I do not think so), is there a workaround to disconnect the
bridged leg after caller hangs up in my agi script?

Hi,

I don't know if my issue is related, but it sure sounds like a similar
problem.
Only difference is that i use AGI as command.
On asterisk-1.6.2.11 everything worked fine for me.

First i upgraded to asterisk-1.6.2.14 and things got weird. 
After peer (originator) disconnects the call, asterisk does not SIGHUP
AGI script right away. Delays for 1-2 sek.

After upgrade to asterisk-1.6.2.15, AGI process is not killed at all.
Even though peer (originator) is already disconnected.

I checked SIP logs and peer sends BYE and asterisk replies ACK.
But AGI process is still running and preforming post-call tasks.
