Your telephone can support up to 12 DECT 6.0 cordless handsets (AT&T model
TL86003, sold separately), or up to ten cordless handsets and two
DECT cordless headsets (sold separately).
Visit www.telephones.att.com/headsets for a list of compatible
DECT 6.0 cordless headsets. Each new cordless handset or headset must be
registered to the telephone base before use. You must register each cordless
handset and headset separately.
