1.11.8 Trunk Call Limitation
Description
Trunk calls are limited by the following features:
Feature Description
Extension-to-Trunk Call
Duration If a call between an extension user and an outside party is
established, the call duration can be restricted by a 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.
Trunk-to-Trunk Call (except
Unattended Conference Call)
Duration If a call between two outside parties is established, the call duration
can be restricted by a 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 trunk-to trunk call were established by
an extension (e.g., an extension makes a trunk call, then transfers
the call to an outside party), the time limit applied to the trunk call that
was made first will be used.
Budget Management When the preprogrammed call charge limit has been reached, an
extension user will hear 3 warning tones at five-second intervals. It is
programmable whether the line is disconnected after the third tone.
After the call has ended, the extension user cannot make further trunk
calls until the charge limit has been increased or cleared by an
extension assigned as a manager (
®
1.9.2 Budget Management).
Dialling Digit Restriction
during Conversation While engaged in an incoming trunk call, the dialling of digits can be
restricted. If the number of dialled digits exceeds the limitation, the
line will be disconnected.
Conditions
•
During an Unattended Conference Call, the Unattended Conference Recall time is applied. (
®
1.14.1.2 Conference)
•
When using LCO trunks that do not support Calling Party Control (CPC) signal detection (
®
1.11.10 Calling
Party Control (CPC) Signal Detection), the Trunk-to-Trunk Call Duration timer should not be disabled, as
automatic end of call detection cannot be performed.

For SIP Extension users, the line will be disconnected without hearing any warning tones when the trunk
call limitation expires.
