Feature Description
CO-to-CO Line Call (except
Unattended Conference Call)
Duration
If a call between two outside parties is established, the call duration
can be restricted by the system timer selected for each trunk group.
Both parties will hear warning tones at five
-second intervals starting
15 seconds before the time limit.

When the time limit expires, the
line will be disconnected.
If both parties involved in the CO-to-CO line call were established by
an extension (e.g., an extension makes a CO line call, then transfers
the call to an outside party), the time limit applied to the CO line call
that was made first will be used.

be
restricted. If the number of dialed digits exceeds the limitation, the
line will be disconnected.

Description
An
extension user can establish a conference call by adding additional parties to an already existing two-party
conversation. This PBX supports three-party through eight-party conference calls. Conferences with more than
four parties are only possible when a PT or PS user originates the conference.
Unattended Conference:
The conference originator can leave the conference and allow other parties to continue. Establishing an
Unattended Conference allows the originator to return to the conference. Unattended Conferences can only
be established by PT and PS users.
