1.2.1 Making Calls
3.1.15 CO Line Call Limitation
Description
CO line calls are limited by the following features:
Feature Description
Extension-to-CO Line Call
Duration If a call between an extension user and an outside party 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. COS
programming determines whether this feature is enabled or disabled.
Whether this feature applies to outgoing calls only, or to both outgoing
and incoming calls is determined through system programming.
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.
Dialing Digit Restriction
during Conversation While engaged in an incoming CO line call, the dialing of digits can
be restricted. If the number of dialed digits exceeds the limitation, the
line will be disconnected.
Conditions
•
During an Unattended Conference Call, the Unattended Conference Recall time is applied. (

•

(Calling Party Control) Signal Detection), the CO-to-CO Line Call Duration timer should not be disabled,
as automatic end of call detection cannot be performed.
