3730 DECT Phone Issue - Phones Won't Subscribe, Stuck on "Searching"

[jokermia]

IP Office R11.0.4.0.3(3), Essential Edition with 1400 series desk phones and 3730 DECT phones. Twelve 3730 phones were removed from a recent install (the customer cut down on the number of phones they wanted at the last second) so they were sent back to be used with another install. All phones have been added to the phone system config and the Master base station like normal, but none of them will connect, staying stuck in the "Searching" mode. In addition, the ADMIN menu of the 3730 phone doesn't show the Factory Reset option, instead just listing the software, hardware, and IPEI information.

Any ideas? If more information is needed, please advise and that info will be provided. Thanks in advance for your help!

I think because the phones are still registered in the previous system, you have to unsubscribe the phone before proceed with the new one.
