AT&T SB67138 pairing cordless sets

If you are having trouble pairing cordless handsets to a AT&T SB67138 (also known as SyncJ), this video will help. The problem comes in when the handsets have been previously registered to another base.

There is a undocumented procedure ot clear the old pairing off the cordless handset making it free to re-pair to a base.

I’m one of the few people left with a landline and had to get a new base for my cordless phones. Couldn’t figure out how to pair them all and came across your video and it worked! So glad this video exists cause it’s still relevant! Thanks!

I have a different problem. I have AT&T EL52500 5 phone system. All of a sudden I cannot call out, but I can receive calls. I switched base stations, but I haven't any idea how to deregister my five phones, and then register them to the new base set. Any ideas how to do that. Thanks-Rod
