[cisco-voip] Conferencing Codecs Across WAN

[Chris Ward (chrward)]

First off, whoever hits the conference button, that's whose MRGL we will
use to choose a CFB/DSP.

To your question, the region settings between site A and Site B will
determine the codecs. You just have to assign the proper regions to your
Conference resource via the Device Pool.

Hi all,

Have a bit of a conundrum that I can't find information on.

If I have two sites, sites A and B and site A has DSP resources for
conferencing installed on the router.

Calls within each site are G.711 and to between each other are G.729.
Now if two phones in site B make a call to each other (G.711) and then
one of them initiates an ad hoc conference to a phone in site A. The DSP
in site A will get invoked but my question is, what will be the codecs
going from site B to the DSP in site A, will it be G.711 as that was the
original codec or will it be G729 because of the region configuration
inherited from the device pool?

1 phone -Site A(DSP Farm) <-----> Site B- 2 phones

Thank you,

Jason
