Try the following steps to resolve the issue:

1) Change to IOS enhanced.

2) Reset CFB in CCMAdmin.

3) Configure "no dspfarm" on the voice-card.

5) Give "no sccp", and then "sccp". Now give "no dspfarm" and then "dspfarm" (global command).

6) Conference bridge needs to be configured as "Cisco IOS Enhanced Conference Bridge Hardware"

7) Reset CFB again in CCMAdmin after each change.

If u r using the PVDM2 in motherboard for the DSPfarm the minimum IOS version required is 12.3(11)T. I think then only u will get the option Version CCM 5.0.1 in SCCP CCM Identifier version .. command.

and u can use these commands for troubleshooting..

1. show running-config

2. show sccp ccm group [group-number]

3. show dspfarm profile [profile-number]

4. show dspfarm all

5. show sccp

6. show sccp connections

7. show media resource status

You must put the version at the end of the line as shown above, that is how I fixed it.

For this to work on CCM 5.X and 6.X, you should use the version 4.1, it should look like this:

sccp ccm identifier 1 version 4.1
