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.

Tandem Trunking allows an extension user to join two outside callers in a Trunk-to-
Trunk Conference. The extension user can then drop out of the call, leaving the
trunks in an Unsupervised Conference. The extension user that established the
conference is not part of the conversation. The conference continues until either
outside party hangs up. In addition, the extension user that set up the conference can
end the tandem call at any time.
The number of simultaneous conference calls is limited by the number of conference
circuits in the system. Due to this fact, the maximum number of conference calls
cannot exceed the limits defined below:
The CPUII provides two blocks of 32 conference circuits, allowing each block to have
any number of conferences with any number of internal or external parties
conferenced as long as the total number of conference channels used does not
exceed the block's limit of 32.

If a call can not be completed, send it to a predetermined Ring Group or play
supervisory tones to the caller.
