CME and UCCX, G.729 for local/remote agents?

[samhopealpha]

Hi Everybody, 

Here is the environment

Local site

- CME 8.5 (single node)

- UCCX 8.5 (single node)

- the SIP route point is configured for codec g711ulaw

- Desk IP Phone and CAD

Remote site

- Metro-E connection with local site

- Desk IP Phone and CAD

In UCCX administration GUI, System > System parameters > Media Parameters > Codec

It only allows me to choose G711...

is it possible to enable the G.729 for the local and remote agent?

Thanks in advance

Sam

You would have to add a transcoder to the CME telephony-service configuration. CME could then transcode the call between G.729 and G.711. Personally I wouldn't recommend this; just buy the needed bandwidth for G.711.

Also, be advised that CCX has dropped support of CME in 9.0. If this is a new install you may want to reconsider your deployment model.

Please remember to rate helpful responses and identify helpful or correct answers.

I have added the following in CME to add a transcoder, and restarted the CCX engine.

But the UCCX system parameter > media codec still not allows me to choose G.729.

Did I make something wrong in CME settings?

sccp local GigabitEthernet0/1

sccp ccm 192.168.5.5 identifier 1 priority 1 version 7.0+

sccp

sccp ccm group 1

associate ccm 1 priority 1

associate profile 2 register XCODER

keepalive retries 5

dspfarm profile 2 transcode

codec g729br8

codec g729r8

codec g729ar8

codec g729abr8

codec g711ulaw

codec g711alaw

maximum sessions 2

associate application SCCP

telephony-service

sdspfarm units 5

sdspfarm transcode sessions 15

sdspfarm tag 1 XCODER

Thanks

Hi Sam,

After referring to the UCCX 8.5 install guide,

http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_8_5/installation/guide/uccx851ig.pdf

On page 71 the below note is mentioned,

Note: The Codec field does not apply to deployments with Unified CME.

Thanks,

Anand
