Interrupt Request (IR)
Interrupt Request allows you to break into an on-going conversation after intimating the extension user about the
interruption.
In case of an 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 users of the system.
• 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 him about a new call. If A dials Flash to answer
C’s call before the expiry of the Interrupt Request Timer, A will be in speech with C. B is put on hold and will
get music on hold.
• If A does not dial Flash before expiry of the timer, C’s call will be disconnected.
• After the conversation between C and A is over and C goes on-hook, speech between B and A will be re-
established.
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.
• 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 system.
• “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.
• “Priority” : No Interaction with Interrupt Request. If 'A' has lower priority than 'B' but has Interrupt Request
enabled; A can interrupt B.
