I'm having a hard time finding information on configuring the DSP chip to transcode an incoming G729 SIP trunk call to the G711 CUE SIP trunk. Here are the commands on the CME I have regarding transcoding. What am I missing? This is an all CME config, no CCM involved.
voice service voip
allow-connections sip to sip
no supplementary-service sip moved-temporarily
no supplementary-service sip refer
redirect ip2ip
voice-card 0
dspfarm
dsp services dspfarm
dspfarm profile 1 transcode
codec g711ulaw
codec g711alaw
codec g729ar8
codec g729abr8
codec g729r8
maximum sessions 22
associate application SCCP
Thanks in advance, this one has stumped me.

Looks like you're missing a lot of configurations. Follow this guide:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmetrnsc.html
You look like you're still missing all the sccp and telephony-service commands.
Here is a sample:
voice-card 1
dsp services dspfarm
sccp local FastEthernet 0/1
sccp
sccp ccm 10.5.49.160 identifier 1
sccp ccm group 123
associate ccm 1 priority
associate profile 1 register mtp123456792012
keepalive retries 5
switchover method immediate
switchback method immediate
switchback interval 5
dspfarm profile 1 transcode
codec g711ulaw
codec g711alaw
codec g729ar8
codec g729abr8
maximum sessions 6
associate application sccp
telephony-service
sdspfarm units 1
sdspfarm transcode sessions 40
sdspfarm tag 1 mtp000a8eaca80
sdspfarm tag 2 mtp123445672012
Please rate if it helps. Thanks.

Thanks! I got it working finally, I needed to use use "sccp ccm 10.5.49.160 identifier 1 vesrion 7.0" and I only need one tag at the bottom. Thanks again!

Ok, I got it working on two 2851's and a 3845, but on my 2 2801's I can't put the "dspfarm" command under the voice-card 0. This is the only difference in the config, but the PVDM's won't associate. The reason for the command not being there, I figure is because the 2801 doesn't have an NM slot? Possibly the reason for the non-association is due to PVDM2-8 & 16 on the 2801 vs. PVDM2-64 on the others? Let me know if you have any ideas.

Hi, I'm trying to get this to work on my 2821 with an NME-CUE and CUCM 7.1.
I think I've got as far as above but how do I tell the phone to use the transcoder? I've set it up as under 'Transcoder' and 'Cisco IOS Enhanced Media Termination Point' and added it to the MRG with device pool of the phones and added the CTI ports into the group.
My CIPC can hear unity but my 7941G just gets silence when calling unity.
Thanks!
