[asterisk-users] Asterisk and G.729 codec: short questions
Dear all, I have Trixbox 2.6 (Asterisk 1.4) installed in my voip server. I have the following short questions about the usage of G.729 codec: 1) Does Asterisk have installed the G.729 codec by default ??? 2) If I don't want to pay for a codec license, using Asterisk in "pass-through" mode for G.729 voice communications, do I just have to download the open source version of the G.729 codec or can I use the one coming in Asterisk ??? 3) If I use G.729 for voice communications and GSM for voice mail sounds, does Asterisk execute trascoding ??? Really thanks Alejandro -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20090721/93d64237/attachment.htm

You only really need the codec module if you're having Asterisk play prompts or record calls or transcode to/from G.729.> 3) If I use G.729 for voice communications and GSM for voice mail > sounds, does Asterisk execute trascoding ???It will, if you have added the G.729 codec. -- Jared Smith Training Manager Digium, Inc.
