3.1.15 CO Line Call Limitation

Description

CO line calls are limited by the following features:

Feature

Extension-to-CO Line Call Duration

CO-to-CO Line Call (except

Unattended Conference Call)

Duration

Dialing Digit Restriction during Conversation

Description

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.

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.

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. (→ 3.1.16 Conference)

•When using LCO lines that do not support Calling Party Control (CPC) signal detection (→ 3.1.20 CPC (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.
