Fractional T Configuration

[relia]

Some quick stats:

CCM v4.1.3

CG 2811

IOS 12.3.5T

VM VWIC-1MFT-T1

This is normally pretty basic but I am somewhat unfimilar with how to handle it on Callmanager. I have a PRI circuit coming in. My voice channels are riding channels 1-11, 12 being the D channel. 13-24 are data.

I cannot find anywhere in callmanager as to how to configure this. Should I just go into the gateway and do it by hand? Any time I make a change on the gateway by hand it appears to "break" the config that is controlled by Callmanager.

Any ideas would be greatly appreciated...

I think I may have answered my own question already.

Under Advanced service settings B Channel:

S0/SU0/DS1-0@mgcp.abc.com = 000000000000111111111111

Could someone verify if this would actually work? What would happen as a result to my data channels?

I also know that there is a known bug open in Cisco to track Fractional MGCP support can some could explain the technical reason why MGCP backhaul is not supported with fractional?
