As the previous posts indicated you can from the CCR have one option to transfer to the other location or to the operator for the other location .If you want to have only one VM handling both systems ,then you will need to upgrade both system to rel 6.o or above and the VM should be NAM 4.1 By this way you can have centerlized VM.You will need the connection between the location to be PRI and you will have to enable a MCDN (network CODE)code for both systems.I hope that helps.
