AdminGuide:Service:Blind Call Transfer

Blind Transfer

Description

This service allows a user (transferer) to directly transfer a call with a third party (transferred) to another PBX user. When blind transfer is used, the transferer loses control over the call as soon as they begin the transfer.

If the addressee of the blind transfer does not answer the call (busy, not available, not registered), the failover action set for that specific extension in the Extensions page is executed.

Default configuration of the failover action in case of blind transfer is Return to transferer. In this case the call is returned to transferer and the prefix “R:” is added to the CallerID to notify that it is a return of a call transfer.

As for every on-call service, blind transfer requires that Direct Media is not enabled for the ongoing call.
If Direct Media is enabled, blind transfer can be done using the specific function key available on the IP phone.

From an operative point of view, blind transfer can be performed by dialing the configured on-call service code (by default #4).
KalliopePBX will play audio instructions and ask for the addressee extension number.
Transferer will then dial the addressee extension number and press # key or wait for default timeout (2 seconds).
In the meanwhile the transferred party will hear an on-hold music configured in the tab Music on Hold.
When the addressee answers, he is on call with the transferred and the blind transfer is complete.
