g723 is supported by Asterisk. I've never used it, but it shows up with the "show codecs" command. > If I choose G.729A the "pass-throu" calls among users are OK, but > Asterisk can't transcode GSM to G.729A in voicemail calls. Because you don't have a g729 codec? > My company doesn'y want to pay for a G.729 license, so I'm thinking to > buy new IP phones with GSM support, so I have no problem with the > voicemail system. You may want to rethink this. G.729 licenses are only $10 per channel. Can you replace the instrument and retrain your users for $10 each? > (Maybe in the future I need to connect the Asterisk with the PSTN, GSM > doesn't matter at this point ???) That would depend on how you interface to the PSTN.
