In my experience when you run out of g729 licenses additional calls will fail.   Simple as that.   Make sure you run out of licenses.

Subject: [asterisk-users] G729 - what happens if licences used up?

I haven't been able to find the answer online, and am not currently able to conduct an experiment to find the answer...

I understand that in a SIP call where G729 has been negotiated as the preferred codec, a G.729 licence is not consumed until there is a need to perform transcoding, e.g. play a non-g729 sound, or do voicemail, or enter a Meetme, etc.

What happens when a SIP call in progress needs a G.729 licence and they are all in use already? Does the call fail, or go silent, or do a re-INVITE to negotiate another codec?

I'm interested in what happens on Asterisk 1.2 (for a legacy system), and also whether it is any different on later versions.
