Tandem Ringing - NEC Electra Elite IPK II System User Manual

Electra Elite IPK II
Description
Tandem Ringing allows an extension user to have two telephones with one telephone number. For
example, extension 105 (the master telephone) sets Tandem Ringing with extension 106. When
extension 105 receives an incoming call, both extensions 105 and 106 ring. Callers would dial the
master extension number (extension 105 in this example). When either the master telephone or slave
telephone is in use, the other telephone cannot be used for outgoing calls or incoming calls.
The multiline terminal must be paired with either a single line telephone or a Wireless – DECT handset.
It cannot be paired with another multiline terminal.
A single line telephone must be paired with another single line telephone or a Wireless – DECT handset.
It cannot be paired with a multiline telephone.
