Hi,
I have to set call length to 3min, but before hangup have to warn
caller. There are many IVRmenu and submenu options with different
warning audio.
I have to measure somehow the audio file length and subtract it from 3
minutes.
exten => _X.,1,Set(_AudioLegth=MeasureAudioLength(WarningAudioX))
exten => _X.,n,Set(TIMEOUT(absolute)=${${MaxCallDuration}-${AudioLength}})
Any idea?
Thank you!

The documentation I have indicates that if there is an extension T in the context, that extension is used at the absolute timeout. So, would: exten => T,1,<play your warning message> exten => T,n,Hangup work? HTH, -- Bob Smither <smither@c-c-i.com>
