Matrix PRASAR UCS - Interrupt Request (IR)

930 Matrix PRASAR UCS System Manual
Interrupt Request (IR)
What’s this?
Interrupt Request allows you to break into an on-going conversation after intimating the extension user about the
interruption.
In case of an important or urgent trunk call the operator can put the call on hold, interrupt the busy extension user to
inform about the urgent call and then transfer the urgent call.
How it works
• A, B and C are extension users.
• A and B are talking to each other.
• C calls A.
• C gets busy tone.
• C dials Interrupt Request feature code.
• C gets Ring Back tone (RBT) and A gets beeps indicating a new call.
• To answer C’s call, A must dial Flash/Transfer before the expiry of the Interrupt Request Timer. A will be in
speech with C. B will be put on hold and will get music on hold.
• If A does not dial Flash/Transfer before expiry of the Interrupt Request Timer, C’s call will be disconnected.
Feature Interactions
• Call States:
• Interrupt Request works only if the dialed extension is busy. The dialed extension may be busy with
another extension or trunk (external number).
• Interrupt Request works only if the user about to be interrupted in is in a two-way normal speech with
another user or external party. However, it will not work if the conversation is being recorded.
• It will not work if the busy signal is due to the user being Off-hook, or in the middle of dialing, or
accessing a feature of the PRASAR UCS.
• “Call Toggle”: Once A and C comes in speech with each other, A can toggle between B and C using Call
Toggle feature.
• Privacy against Interrupt Request: If the feature 'Privacy against Interrupt Request is enabled for an
extension, it cannot be interrupted. See “Privacy”.
• “Priority”: No Interaction with Interrupt Request. If 'A' has lower priority than 'B' but has Interrupt Request
enabled; A can interrupt B.
