Replacing a speakerphone

You may need to deregister your speakerphones if:

You want to register your speakerphone to a different

telephone base.

-OR-

You already have two registered speakerphones on the telephone

base and need to replace one of them.

-OR-

You wish to reassign the designated speakerphone number.

To do so, you must deregister all the speakerphones and then

individually register each speakerphone again.

Please read carefully through all the instructions on this page

before beginning the deregistration process.

Deregister all speakerphones

To deregister all speakerphones from the telephone base, follow

the instructions in the user's manual of your telephone system,

or visit our website at www.telephones.att.com.

This operation will deregister all the DECT handsets, headsets,

and cordless speakerphones, regardless of their battery status

and whether they are within range or out-of-range.

NOTE: You cannot deregister the speakerphone(s) if any system device is

in use.
