I am making a call between two asterisk servers via sip uri. The call hangups after 3600 seconds. I have set the absolute timeout to 7200 seconds in my agi.
$max_duration = 7200;
$agi->set_variable(“TIMEOUT(absolute)”,"$max_duration");
The origination server is initiating the hangup request at exact 3600 secs. In wireshark trace, I found
X-Asterisk-HangupCause: Normal Clearing
X-Asterisk-HangupCauseCode: 16
Is there any other parameter which can hangup the call?
