The real topic here is that g729 is necessary because some part of your setup requires g729 or g723 to achieve low bandwith consumption while the whole "old fashioned" telephone industry works with g711 g729 g723 and we still use this to terminate our PSTN traffic.( Not yet iLBC or GSM or speech or G726).
ilbc is supported by many sip phones and also at least by asterisk and sems pstn gws. it may just be a short matter of time before ilbc support is also in cisco gws, since cable labs recently chose it for use in cable modem voip adapters.
So in stead of discussing the implementation of G729 or G723 over and over again it is maybe time to form a workgroup that tries to achieve a transparent opensource replacement of mentioned codec's that can be used in whatever application.
see above. i consider it better to push ilbc to all major sip phones and gws.
