Tandem Ringing
Description
Tandem Ringing allows an extension user to have two telephones with one phone number. For
example, extension 305 (the master phone) sets Tandem Ringing with extension 306. When exten-
sion 305 receives an incoming call, both extension 305 and 306 ring. Callers would dial the master
extension number (extension 305 in this example). When either the master phone or slave phone is
in use, the other phone cannot be used for outgoing calls - incoming calls, however, will ring the
available phone.
The keyset must be paired with either an analog single line telephone or Aspire Wireless extension.
It cannot be paired with another keyset or IP phone.
Conditions
(A.) The slave phone cannot call the master phone.
(B.) Extensions numbers up to 8 digits can be registered on the Tandem Ringing key. Extension
numbers over 9 digits cannot be registered.
(C.) If both phones are busy, no additional calls can be received.
(D.) Tandem Ringing can support up to 256 pairs of Tandem Ringing extensions.
(E.) The extension user which enables Tandem Ringing is the master, while the slave phone is the
extension entered by the user while setting up the feature.
Default Setting
Disabled.
