Are current setup is that the main site is an H323 gateway and all the remote sites are MGCP gateways. Our main site currently has 5 PRI's. The telco is wanting to take one of our PRI's and divide it up into 3 different groups of 8 channels each due to some local dialing issues (local calls actually have to be dialed as LD for some sites and not for others depending on what area of the county you are in). Is this possible? Has anyone done this before and if so how difficult is this to implement. We are currently running CUCM 6.1.1.
To my knowledge this can't be done with a PRI since you can only assign one pri-group to a controller. However, if this is actually a T1 CAS circuit (indicated by the fact you mention 3 groups of 8 channels=24) I think you could use 3 ds0-groups, although I have never done what you describe. Are you sure thay are talking about a PRI? You aren't running NFAS on this are you?
