[asterisk-bugs] [JIRA] (ASTERISK-28289) Feature: Allow detection of inband progress for outbound channels

[Corey Farrell (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-28289?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Corey Farrell updated ASTERISK-28289:
-------------------------------------

    Attachment: func_sit.c

func_sit.c is functional (DSP issues aside).  Not ready for gerrit yet - it needs xmldoc for the function, probably needs to handle arguments for enabling busy/congestion detection.

> I've created a dialplan function which adds a framehook to detect inband progress tones in pre-media of outbound channels.
> My current implementation is a dialplan function which adds the framehook, so dialplan might be as follows:
> {{noformat}}
> [sit-hook]
> exten => s,1,Set(SIT_WATCH()=1)
> same => n,Return()
> [default]
> exten => _X.,1,Dial(${TRUNK}${EXTEN},30,b(sit-hook^s^1))
> {{noformat}}
> The value set to SIT_WATCH is currently ignored, in the future this might allow specifying which types of tones should be recognized.  So far I've tested using Local channels calling Playtones without answering.  The busy and congestion tones both result in DIALSTATUS=BUSY.  The 'info' tone results in DIALSTATUS=CONGESTION.
> I have not been able to test against a "real" busy or fast busy call, I have tested against a call that plays the info tone (beep-beep-beep the number you have dialed is out of service).  This is not detected as CONGESTION.
