You can use the the 4.1 identifier and it will work just fine.

For what it worth, this the the config I'm using and it works perfectly fine. This is a 3845 running 12.4(11)T1 and I run CM 5.1

voice-card 0 (whatever board you are using)

sccp local GigabitEthernet0/0

sccp ccm X.X.X.X identifier 3 (I don't use version numbers and it works perfectly fine. I believe it actually defaults to 3.1)

IOS version in ur router is 12.4(11)T That makes the difference.For enhanced conference

in 2800&3800 using PVDM2 needs minimum IOS version of 12.3(11)T
