Callmanager 5 and enhanced dsp conference bridge

[miket]

I am trying to add a hardware conference bridge on a callmanager 5.1 using a 2801 . I have it all configured and when I try to add the ios enhanced CFB in callmanager I get a cc_register_failed

what am I missing..

ios og 2801 is 12.4.13t

When you build the CFB SCCP identifiers what CM version do you specify?

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)

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
