I know we can't order these any more, but going through my license bank I have several P/N 54004029 "5000 ICP: IP End Point Unit License" for MiCollab... Can these be applied to an app record and used for 53xx phones? I also have a few 840.0415 "IP Phone Cat C License" and some 840.0417 "MiVoice Office License - Dig Phone Cat E", those perhaps?
I know there is some flexibility with some of these licenses, but I can't remember where they can crossover.
