Hi,
 
I’m using FS with g279 on passthrough mode and I’m trying to play a g729 file as ringback to the A-leg while bridging a call.  As far as I understand it should go something like this:
 
·         originate {channel_vars}dialstring
·         set some combination of values on ‘ringback’, ‘transfer_ringback’, ‘instant_ringback’
·         bridge <bridge_destination>
 
The bridge works correctly, but no matter what combination of values I try for the ‘xxxringback’ vars I never hear the ringback on the A-leg.
 
Can you tell me what I’m missing?
 
Thanks.
