PBX Integration Board User’s Guide

Aborting the Transfer

A transferred call can be aborted at any time (prior to completing the transfer)

by pressing the appropriate appearance key where the original call resides.

The application can perform this only in a supervised transfer mode. For

example, if the original call resided on the first appearance (Feature Key 09),

dialing

dx_dial(<ESC>KA) will bring the original caller back to an active

state.

Example

An application answers a call and plays a greeting message prompting the

caller to enter the extension she wish to reach (the caller enters 221). Using

the

dx_dial( ) function with the dial string (&,221), the application attempts to

transfer (supervised) the call to extension 221. Call progress analysis is used

to determine if extension 221 is answered, busy, or there is no answer.

extension 221 answers, the application hangs up and the transfer is complete.

If the extension is busy or not answered, the application reconnects to the

incoming call and plays a message asking the caller to choose between

accessing voice mail or transferring to the operator.
