alberto.orden · ‎02-12-2008

Hi to all,

If we change the codec in the call manager 4.2(3) in the regions from g711 to g729, do i have to do something else in the cisco unity 4.2(1)

regards

Alberto

Hi Alberto,

Yes, the required steps are outlined in this guide;

Hope this helps!

Not necessarily...

Unity performs fine in a multi-codec environment.

If Unity is currently configured for G.711 then you will need to make sure that calls coming into the Unity at from a remote site using G.729 are transcoded to G.711.

Please see the following document (contains configuration details and a good diagram)

Hi

You may also enable support for G729 thru the advanced settings tool in the unity tools depot
