Re: [Asterisk-Users] G729 question
My understanding is that if the codec type matches on each leg of the call then Asterisk is using pass through. The PBX simply has to relay the RTP packets unchanged from one device to another. If you are going from a phone using codec tupe A to codec type B, Asterisk must perform a conversion which requires support for both codecs. iTS [EMAIL PROTECTED] wrote: Hi, where can I find info on configuring pass-through mode. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of SW Sent: Jueves, 18 de Diciembre de 2003 11:29 p.m. To: asterisk users Cc: Clif Jones Subject: [Asterisk-Users] G729 question Hi Clif, My experience with G.729 and asterisk is not good. My first registration was good, it worked. Then I bought more license and tried to upgrade it, it blew everything off. Still waiting Digium support to give me a helping hand. If you use pass-through feature then I guess you are fine. I have SIP users going to h.323 g/w and I need g.729. So now I have it in pass-through mode, I think that requires less CPU overhead and I do not have to mess with licenses.

Which G729 codec is sold by Digium for Asterisk, G729, G729A, B...I? 2. If I have G729A on one end and G729B on the other, are they compatible? I have looked all over the place for question 2, but without buying the ITU docs I cannot seem to find this answer. I know that G729A is low complexity which seems to be what Cisco 7960's use but I have some others that support G729B which has comfort noise and reduced transmission during silence. If anyone knows how the different G729 codecs interoperate I would be eager to know.

Re: [Asterisk-Users] G729 question
Found it. Anyone interested can look in RFC3551 RTP Profile for Audio and Video Conferences with Minimal Control. You can piece together that G.729, G.729a G.729b will play together and the other annexes will not due to bandwidth differences.
