asterisk users - May 2006 - IVR & transcoding & g729 license

Hello,

- a call comes in with protocol SIP, codec g729
- connects to the IVR [playing prompts, collecting digits]
- dialing forward to protocol IAX2, codec g729

I guess, while the call is in IVR, I need one g729 license for the call.
If the call leaves the IVR, thus dials to another box with the same g729
codec, will it need 2 licenses? While there should be no transcoding
further, will it free up the codec which was used during IVR session?

I would like to avoid useless transcoding [g729->slin->g729] in case the
call goes through an IVR.

How is such case handled in asterisk? [1.2]

Thanks in advance,
	Tamas

Tamas,

	Just record your IVR prompts in g729 (or convert them to g729 from some 
other format)!
