'support' - yes, 'licenses' - no. Asterisk supports passthrough, recording and playback of quite a few codecs for which there are no transcoding modules available at all (G.723.1, H.263/4, etc). G.729 falls into this category if there is no transcoding module loaded, or if there are no licenses available. The only time that Asterisk will not offer G.729 in an outbound negotiation is if the incoming channel is not in G.729 (so thus would require transcoding) and there is no transcoding path available. The same is true for other codecs that don't have transcoding available... but by definition, this is not 'passthrough'. Also, to clarify an earlier point, Digium makes all the standard Asterisk prompt sets available in G.729 format, so the built-in applications can be used on G.729 channels without requiring transcoding. -- Kevin P.

Re: [asterisk-users] Question about g729
My understanding is that Asterisk will not pass through calls in codecs for which it does not have support and/or licenses; it simply does not advertise them in the SDP negotiation.

Re: [asterisk-users] Question about g729
However, I've read somewhere that passthrough doesnt require a license. Which means that if your sip clients can transmit in g729 and your voip provider can receive in g729, your asterisk server won't need to do any encoding and therefore doesn't need any licenses. It is simply passing the data through from your sip clients to the voip provider. Not sure what happens if you want to play recorded messages and things. It would probably need licenses then because its encoding.

Re: [asterisk-users] Question about g729
You pay per channel. Which I believe to mean, if you have 10 sip clients but only 2 clients make calls at the same time, you only need 2 licenses. You only need to purchase 10 licenses, if all 10 clients will be making calls at the same time. I hope that makes sense. Maybe someone can explain it better or correct me if Im wrong.

I am currently testing an asterisk server using the default codecs, I have allow=all, and noticed everytime I test it in a wireless lan the latency rockets off the roof to over 1000ms. I would like to test g729 since it uses less bandwidth but, read somewhere I have to buy a license per every channel I have. Does this means if I have my server connected with 10 sip clients I need to buy a license for 10 or more? ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users ___ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
