I ran into a similar problem (running out of licenses) today, the result 
was one way audio. Have you got call recording enabled on any of the 
extensions that participate in the conference? I have two g729 licenses 
and ran out of licenses making a single call from a single SIP device. 
Not sure (yet) why more than two encoder/decoders would be needed to 
handle a single call with recording. There are similar problems being 
reported recently on the Trixbox list, but it sounds like they may be 
related to the Trixbox compile of the latest Asterisk.
