[cisco-voip] Transcoder question

[David Lima]

Hi Peter, thanks for your reply

Remote (assigned to DP-B?) and [let's call it HQ] (assigned to DP-A?) Please
let me knwo if this is correct.--->you are right

I imagine that between these two regions, you have g.729 configured.---> you are right

I imagine that between DP-A and DP-A, in other words, _within_ DP-A,
you use g.711-----> you are right

My router 2801 for conference and xcodec resources are located in Region_A where my CCM, PSTN Gateway and iGATE are located. I have the Media resources configured and active, From remote region (Regiona_B), calls to ip phones located in the Region_A or to PSTN are normal, but when a call is dropped when it go through the iGATE (configured as H323 in my CCM). When I press twice the "?" button on my ip phone, I can see that there is TX Packets but the RX packets remains in 0.
Thanks again
David

David,
   I understand that you have two physical locations - Remote
(assigned to DP-B?) and [let's call it HQ] (assigned to DP-A?) Please
let me knwo if this is correct.

I imagine that between these two regions, you have g.729 configured.
I imagine that between DP-A and DP-A, in other words, _within_ DP-A,
you use g.711.

Please check and make sure what I'm assuming is correct.

Please tell us:
The _physical_ location of the 2801 used for conferencing/transcoding
The _physical_ location of the gateway used to connect to the PSTN

the device pool the gateway is in, (check this under the gateway config menu)
the device pool the transcoder is in (check this under the media
resources > transcoder menu)

Please confirm that you're using an H.323 gateway for PSTN access

Once you've given us this information, we can provide some answers as
to what's goign on, but i will need that information to tell you what
you need to go look at first =)

Lookin' forward to helping,
-Pete
