Michael Cargile updated ASTERISK-26681:
---------------------------------------

    Description: 
Local Channels created with an AMI Originate are not optimizing when connected, even with 30 seconds of Wait. In Asterisk 11 they usually did this within 200ms.

Here is the relevant dialplan:
{noformat}
exten => _91NXXNXXXXXX,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _91NXXNXXXXXX,2,Dial(SIP/office-server/${EXTEN:1},,To)
exten => _91NXXNXXXXXX,3,Hangup

exten => 8368,1,Playback(sip-silence)
exten => 8368,n,Wait(30)
exten => 8368,n,DumpChan()
exten => 8368,n,AGI(agi://127.0.0.1:4577/call_log)
exten => 8368,n,AGI(agi-VDAD_ALL_outbound.agi,NORMAL-----LB)
exten => 8368,n,AGI(agi-VDAD_ALL_outbound.agi,NORMAL-----LB)
exten => 8368,n,Hangup()

exten => h,1,AGI(agi://127.0.0.1:4577/call_log--HVcauses--PRI-----NODEBUG-----${HANGUPCAUSE}-----${DIALSTATUS}-----${DIALEDTIME}-----${ANSWEREDTIME})
{noformat}
Here is the SIP entry:

In Asterisk 11 and earlier Local channel optimization was triggered during audio processing. I am not sure if that is still the case now that it has been moved into the Core, but I have confirmed that there is audio on these calls.

It would actually be great if the LocalOptimizeAway actually triggered an optimization rather than just clearing the 'n' flag from the channel. Either that or there was a dialplan application that would force an optimization of a Local Channel.

  was:
Local Channels created with an AMI Originate are not optimizing when connected, even with 30 seconds of Wait. In Asterisk 11 they usually did this within 200ms.

Here is the relevant dialplan:

In Asterisk 11 and earlier Local channel optimization was triggered during audio processing. I am not sure if that is still the case now that it has been moved into the Core, but I have confirmed that there is audio on these calls.

It would actually be great if the LocalOptimizeAway actually triggered an optimization rather than just clearing the 'n' flag from the channel. Either that or there was a dialplan application that would for optimization on a Local Channel no matter what.
