SOLVED Call Forward on No Answer doesn't seem to be functional.

[hfoster]

Anyone else on a relatively recent release notice the Call Forward on No Answer doesn't work? For example, here's an extension that has it enabled. (No other follow mes or forwards for simplicity)

However later on in the call it seems to jump right over the app.lua failure_handler script which should forward to the mobile, 07933333333. Instead it falls through to the voicemail handler instead. There's a full log attached if you want to look at it, but I don't think it highlights much else. I suspect the problem is the failure_handler LUA not knowing the error ALLOTTED_TIMEOUT. Really not that familiar with FreeSWITCH lua scripts to say for definite and there hasn't been any commits to it for a long time.

Hey, as far as i know the no answere forward only works if the hangup cause (or maybe originate_disposition) is "NO_ANSWERE".
It does look like you have "ALLOTTED_TIMEOUT".

 

[hfoster]

Bizarre, I didn't think it would use that for a call that is Inbound Route -> Transfer to Extension. I might have to experiment with this failure handler LUA to do it for ALLOTTED_TIMEOUT too.

Thanks anyway, that's solved that mystery.
