Busy Alerter is a Cisco Unified Communications Manager’s application that sends a notification to the calling party when the called line is already engaged. This is necessary when the called line supports two or more calls (busy trigger parameter is greater than one). In this case the phone rings and the caller may think that nobody is answering.

With Busy Alerter when calling from an IP Phone, the caller will get a Popup on the IP Phone screen with a warning message and/or an audio message.

With Busy Alerter, external callers will be redirected to an audio server that delivers a message telling that the other party is already on line. The application gives the opportunity to directly leave a voicemail or try ringing the phone anyway. Different messages can be played depending on the directory number range.
