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.

Cheers

SW

I am thinking about using the G729 codecs on my endpoint devices and
purchasing some G729 licenses for Asterisk but I have several questions:

1. 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.
Thanks.
