Matrix PRASAR UCS System Manual 721
How it works
A and B are extension users.
C is an external caller.
D is an external number.
Call Transfer from Trunk/Extension to Extension
Three scenarios are possible:
1. Screened Transfer:
• C calls a Trunk of PRASAR UCS.
• The Operator answers the call.
• Operator puts C on Consultation Hold.
• Operator dials B's extension.
• When B answers the call, the Operator informs B about the call.
• If B accepts the call, the Operator transfers the call to B.
• Now, B and C are in speech.
• If B does not accept the call, Operator may dial Flash to retrieve the call and speak to C.
• The Operator can also abort call transfer while B's phone is ringing by dialing Flash. The Operator gets
connected to C.
2. Transfer While Ringing:
• C calls a Trunk of PRASAR UCS.
• The Operator answers the call.
• The Operator puts C on Consultation Hold and dials B's extension.
• The Operator transfers the call when B's phone starts ringing.
• If B answers the call, B gets connected to C.
• If B does not answer the call at the end of the Transfer-While Ringing Timer (programmable; default: 30
seconds), the call is returned to the Operator. C gets Ring Back Tone.
• The Operator answers the call and is in speech with C.
• However, if the Operator is busy at the time of call return, the system waits for the Operator to become
free. When the Operator is free, C gets Ring Back Tone.
• The Operator answers the call and is in speech with C.
3. Transfer On Busy:
• C calls a Trunk of PRASAR UCS.
• The Operator answers the call.
• The Operator puts C on Consultation Hold and dials B's extension.
• The Operator gets busy tone from B's extension. B is busy with A
• The Operator transfers the call to B on Busy tone.
• B gets intrusion beeps. The beeps are played for the duration of the Transfer on Busy Timer
(programmable; default: 30 seconds)
• B may dial Flash to answer the call. A is put on hold.
• B is now connected to C.
• If B does not answer the intrusion beeps at the end of the Transfer on Busy Timer, the call is returned
to the Operator. C gets ring back tone.
• If the Operator too is busy at the time of call return, C gets busy tone.
