thank you.. so go to each extension and under provision. remove the mac address and phone? then reset the phone to factory default and let 3cx pick it up and assign it to the correct extension?The phones are provisioned with specific extension details. The correct way if to factory reset, remove the phone from the previous extension and provision to the new.
Founded in 2005, when VoIP was an emerging technology, 3CX has gone on to establish itself as a global leader in business communications.
