To reject a telephone call in the ALERTING state, your CCXML document must use a <reject> element within a <transition> element:
<transition event="connection.alerting" name="evt"> <reject connectionid="evt.connectionid"/> </transition>
To identify the telephone call to be rejected, specify its connectionid in the <reject> element.
The operation of <reject> is dependent on the telephony protocol being used. In particular, when using a CAS protocol the caller will continue to hear the ringing tone and the switch will continue to present the call to Blueworx Voice Response until the caller hangs up.
