[Users] G729 Codec question

[Andreas M.]

Hello,
i have a question regarding codec G729.
We want to implement this in our client software, but there exists many flavours.

Are all G.729 codec flavours compatible to each other?

For example:
G729 to G729A or B ?
or G729B to A and vice versa ?

We are currently using Cisco AS5300 Gateways, that supports G729 and G729B. But we want to change
our gateways, then only G729A is available.


i know this question has nothing to do with openser, but i think there are many readers with experience.

best regards,
Andreas M.
