Where does TMS get CTS URI from when adding systems into TMS from CUCM?

[nickwarfield]

If I add a CTS system into TMS, the URI is XXXX@company.com, and I can't change it.  The XXXX is the DN from CUCM, but where does it get the @company.com from?

The reason I ask is that we need to have the URI be @video.company.com.

Anyone have any idea where this might come from?  I checked Enterprise Parameters, Service Parameters, the phone & DN in CUCM, and I've looked in TMS as well and I can't find it anywhere.  None of the guides I could find had any information about it, either.  

Versions are TMS 15.1 & CUCM 9.1.2.

Thanks

I figured it out.

CUCM-> System -> Enterprise Parameters -> Clusterwide Domain Configuration -> Organization Top Level Domain
