[asterisk-bugs] [JIRA] (ASTERISK-26681) chan_local: Local Channels Not Optimizing

[Michael Cargile (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-26681?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=234484#comment-234484 ] 

Michael Cargile commented on ASTERISK-26681:
--------------------------------------------

I will review the documentation as soon as I have our application working properly on Asterisk 13 and give feed back.

Overall this just shows that I need to stay on top of Asterisk trunk development and provide feedback when things are changing that sound like they will effect how we are using Asterisk. I also probably need to start working on support for new versions of Asterisk when you put out initial release candidates and not when an LTS version is beginning to head towards end of life. If I had before Asterisk 12 was fully release I might have been able to suggest adding a dialplan application for forcing Local Channel optimizations (still might look into developing one for Asterisk 15 or 16).

> 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 CLI output:
> [Edit by Rusty - Removed as per guidelines. Attaching as cli_output.txt]
> 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.
