Lightening recently damaged my AT&T Home Telephone Answering system base station rendering the 3 cordless handsets useless. I purchased an identical Telephone system that comes with 3 handsets and hoped to reuse the handsets fom the old system on the new.
The AT&T TL92370 base station can support up to 12 handsets. However as I read through the instructions on registering and deregistering handsets, it became apparent that to deregister a handset from the base station one needed a working base station to do so. The handsets once registered to a base station cannot be registered to another until they have been released from the original base station. The orphaned handsets displayed the following message
Out of range OR No power at base
I searched in vain on the net looking for a way to remedy this. I diassembled one of the hansets hoping to find a reset switch. No such luck. I was now the proud owner of 3 orphaned handsets I could not use.
I sent an email to AT&T asking how to accomplish this. I got a boilerplate response informing me that my problem was too complicated for email resolution and to call 1-888-883-2442 to speak to a tech. I called using Skype. It took about 8 minutes on hold before I got through to a live tech. He asked basic questions and did understand my problem first time. He put me on hold and came back with the folowing code to enter into the old handsets.
*331734# followed by menu/select
The phone beeps twice, reboots and then comes back up ready to register to a new base station.
Registering to the new base station is now easily accomplished using the standard instructions.
- Press and hold handset locator on base station until ‘in use’ light comes on.
- Press # on the handset and the phone registers itself to the base station.
I repeated the above procedure with my two remaining handsets and now I have a 6 handset cordless system for my home.
It’s important to note that if you have a working base station you should use the standard instructions for deregistering the handsets. Each handset gets allocated a handset number by the base station, if you deregister using the special code detailed in this post then the reserved handset number on the base station is consumed and cannot be reclaimed; thus reducing the number of handsets the base station can support by 1. The special code is only for use when you have a handset that is orphaned from a lost or non-working base station.
