Last year we migrated from a 4.1(3) CallManager to a new CUCM 7.1.3 appliance. We recently discovered a few 7942G phones still boxed with the 1 RTU license (Part# CP-7942G-CH1).
Is there any way to use the RTU license on the new CUCM server? ie: convert the RTU to DLUs?
Also, going forward if/when we order new phones, I assume we should be ordering phones without RTU's and buying DLU's as needed?
