[asterisk-users] Question about hangup - Asterisk v11.15.0

[Administrator TOOTAI]

Hello,

on previous versions of asterisk, extension h and H make us know who 
ended a call (caller or callee). In the last * versions, seems that only 
h extension is used, as stated here 
http://www.voip-info.org/wiki/view/Asterisk+standard+extensions

In the last versions, how do we know which end terminate a call (SIP, 
ISDN, Analog, ...) in h extension ? Will the 
${HASH(SIP_CAUSE,${CDR(dstchannel)})} give the information ?

We also face a strange behavior: we are ringing few phones (~10) and 
sometimes, once the call get answered, we see that 2~3 seconds after 
this, music on hold is started on the channel! And 20 seconds after, the 
call is terminated without that any party hanged up :-(

It's a Elastix 2.5 installation, we thought that problem could came from 
Elastix so we set our own dialplan for incoming calls:

  same = 
n,Set(__phonesToRing=SIP/118&SIP/119&SIP/122&SIP/123&SIP/124&SIP/125&SIP/126&SIP/127&SIP/128&SIP/129&SIP/130&SIP/132)
  same = n(startRing),Answer()
  same = n,Dial(${phonesToRing},,it)                     ;no voicemail 
or forward => ring indefenitely
  same = n,Hangup

Incoming call give for instance in logs:
