Your telephone can support up to 12 DECT 6.0 cordless handsets,
headsets or speakerphones. You can purchase additional handsets
(AT&T model CL80115, sold separately) or up to 10 cordless
handsets and two cordless headsets or speakerphones (sold
separately). Visit www.telephones.att.com/accessories for

Each new handset, headset or speakerphone must be registered to the
