[OSL | CCIE_Voice] Gatekeeper Codec control
Hello everyone. My question today is concerning controlling which codecs are used when utilizing RAS signaling via the Gatekeeper. I understand that I can control my codec inbound (at the BR2 CME) site via a inbound dial-peer that only utilizes g729r8. I also understand that using Transcoding at the same location will allow me to talk to a locally attached SIP phone (at CME site) that is configured to use g711ulaw only. However I am unclear as to how to program the CUCM controlled devices what codec to use when sourcing calls to the BR2 site via gatekeeper. If I am sourcing calls from CUCM across a gatekeeper trunk that has been configured to be in the HQ device pool which is associated with the HQ region which uses g711 intra-cluster... then shouldn't I be sourcing packets from CUCM to BR2 as g711ulaw? Any additional thoughts or clarification would be greatly appreciated. Thanks, Justin McIntyre Engineer Mutual Telecom Services Inc. a wholly-owned subsidiary of Black Box Corp.

Re: [OSL | CCIE_Voice] Gatekeeper Codec control
There is not way to force Codec in CUCM (except setting the lowest bandwidth consumption codec) When you configure Regions settings in CUCM, that actually sets the Maximum allowed codec within/between regions. Not the Codec itself. So for instance, when you set G711 within a Regions, that means that any codec whose Rate is equal or less then 64 kbps will be alowed in that Region (G711, G729, iLBC and etc). When you set region to G729, then the codecs that are using equal or less Rate then the G729 (8kbps) will be allowed, (No G711, No iLBC any more). Now for Gatekeeper - you can use the Bandwidth command, which will make almost the same for allowing codes, For instance you can set Bandwidth Session command to 128 (G711 for GK CAC uses 2x64), so that G711 and lower Bit Rate Codecs can be used. And if you set Bandwidth Session command to 16 (G629 for GK CAC uses 2x8), then G729 and lower Bit Rate Codecs can be used. Hope that helps.

Hi Justin, Create a new Region with 729 codec only, create new Device Pool with this region and assign your trunk to this new Device Pool.
