I have it working: de bas is registered to the CUCM.
I have 3 handsets connected to the base, they all can call.
Only thing: I can create 6 profiles within the basestation.
I also can connect each profile to only one phone.
So it would be ideal if I can setup 3 profiles, one for each handset, with it's own number.
Only thing is that I cannot create 3 phones with the same MAC.
Any idea?
