Registering handsets with the base
1. Press the
Reset
button on the back of the base. A
five-minute registration period starts, which allows
handsets to register with the base.
NOTE: If you have multiple bases, only reset one base
at a time, and wait five minutes before resetting the
next base.
2. If the handset is turned off, press the
Red Phone
key to turn it on.
3. Place the handset in the handset charger. The handset
automatically registers with the base, and the
Configure
SIP Domain
message appears on the display. This
message indicates that you must configure the TS-850i/
TS-860i as an IP extension, as described later.
A base can support up to three handsets with three
concurrent calls. It can support up to eight handsets if
they aren’t all used at once. If you have more than
three handsets and are getting busy signals, add more
bases to your installation in order to handle more calls.
