Tandem Ringing 2 - 811
Tandem Ringing
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 can not 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.
Conditions
The slave telephone cannot call the master telephone.
Extension numbers up to eight digits can be registered on the Tandem Ringing key.
Extension numbers over 9 digits cannot be registered.
If Tandem Ringing is enabled, and one of the extensions is busy, no additional calls can be
received or placed from either telephone.
Tandem Ringing can support up to 128 pairs of Tandem Ringing extensions.
The extension user which enables Tandem Ringing is the master, while the slave telephone
is the extension entered by the user while setting up the feature.
A slave telephone will ignore the settings for DND and follow the master telephone’s
settings instead.
Voice Call is not supported on a multiline terminal with Tandem Ringing.
Calls placed on Hold while Tandem Ringing is active will immediately recall if the handset is
placed on-hook.
When an extension leaves a Message Waiting for a Tandem Ringing extension, both
extensions will indicate the message until one of the extensions return the call.
A slave telephone will ignore the settings for Ring Groups and follow the master
telephone’s settings instead.
To transfer calls between the two Tandem Ringing stations, a System Park Orbit should be
used.
