[cisco-voip] ilbc codec and DevicePool for a Transcoder?

[Anthony Kouloglou]

Hi Peter,
no, devices in central site do not support ilbc (7941G-GE). That is why i
want to ude transcoder.
My transcoder is located at the central site.
The 2 remote devices are registered in the central ccm cluster (7942G).
All devices use g711 in their own device pool and ilbc with the other.
That is what i want to know: where must the transcoder be configured? in
which device pool?

Anthony, we need some more infromation to tell you waht's happening.

can both devices do iLBC? Trying to undesrtand what call flow is
requiing a transcoder.
Where is your transcoder physically located?

what types of devices are involved in the call?
what codecs do the devices at the central site use and what are the
model numbers of the phones in use? they don't all support iLBC.
what device pool/region is the transcoder in and what is configured
between that region and the central and remote site regions?

Hi,
1. i have configured an Enhanced IOS transcoder to be used by several remote
devices that want to use iLBC with the central site.
2. The sccp transcoder is registered with the CUCM 6.1 ok. (ilbc is included
in the sccp profile)
3. I have configured 2 regions one for the central site and one for the
remote. Audio codec between them is iLBC.
4. I have configured a media resource group containing only the above
transcoder.
5. I have also configured 2 device pools: each pool has one region of the
above (step 3)

What must the media resource list be like in order for the configuration to
work?
What is the meaning of assigning a device pool inside the transcoder since
the transcoder is in a MRGL which inturn is used by a device pool?

Thanks a lot
Anthony
