[cisco-voip] CME transcoding issue

[Chris D'amore]

I have two 2811 routers running CME version 3.4. I can't get transcoding
to work between the two CME routers. When I call the Unity Express pilot
number on CME router 2 from CME router 1, I get a fast busy. If I set
the dial-peer to use G.711, it works fine. Below is the transcoding
related configuration from the two routers. Any help you can give me
would be much appreciated. 

CMR router 1: 

voice-card 0 
no dspfarm 
dsp services dspfarm 


dspfarm profile 1 transcode 
codec g711ulaw 
codec g711alaw 
codec g729ar8 
codec g729abr8 
codec gsmfr 
codec g729r8 
codec g729br8 
maximum sessions 12 
associate application SCCP 

telephony-service 
load 7960-7940 P00307020200 
load 7914 S00104000100 
load 7905 CP7905060000SCCP050124A 
load 7936 cmterm_7936.3-3-5-0 
load 7912 CP7912060000SCCP050124A 
max-ephones 20 
max-dn 100 
ip source-address 10.10.1.250 port 2000 
sdspfarm units 1 
sdspfarm transcode sessions 16 
sdspfarm tag 1 mac0015.f98e.01 

CME router 2: 

voice-card 0 
no dspfarm 
dsp services dspfarm 

dspfarm profile 1 transcode 
codec g711ulaw 
codec g711alaw 
codec g729ar8 
codec g729abr8 
codec gsmfr 
codec g729r8 
codec g729br8 
maximum sessions 12 
associate application SCCP 

telephony-service 
load 7960-7940 P00307020200 
load 7914 S00104000100 
load 7912 CP7912060000SCCP050124A 
max-ephones 20 
max-dn 100 
ip source-address 10.10.2.250 port 2000 
sdspfarm units 1 
sdspfarm transcode sessions 16 
sdspfarm tag 1 mac0015.fa2f.75 


I have just added the following commands to my configuration: 
sccp local FastEthernet 0/0.2 
sccp ccm 10.10.1.250 identifier 1 
sccp 
sccp ccm group 1 

When I do a "show sccp all", I see the following: 
Transcoding Operational State: Down - Cause Code: NOT_ACCOC_TO_CCM_GROUP

Active Call Manager: NONE 
TCP Link Status: NOT_CONNECTED, Profile Indentifier:1 

In my running configuration I have the following sccp related commands: 
sccp local FastEthernet 0/0.2 
sccp ccm 10.10.1.250 identifier 1 
sccp 
! 
sccp ccm group 1 
associate ccm 1 priority 1 

10.10.1.250 is the IP address for CME on this router. Fast Ethernet
0/0.2 is the sub-interface the above address is assigned to. 

What is causing the Transcoding Operational State to be Down? 
Thank you for all of your help! 
Chris
