Instead of dropping the call without explanation, you can take a few extra steps to play a message.
On the System Recordings page, select Built-in Recordings and build a recording using these settings:
- Name: Blocked
- Descriptive Name: "We are sorry, the number you have dialed is currently unavailable. Please contact technical support."
-
Files:
- sorry
- the-number-u-dialed
- is-curntly-unavail
- please-contact-tech-supt
On the Announcements page, create a new announcement:
- Name: Blocked
- Recording: Blocked
- Destination After Playback: Terminate call (Congestion)
On the Misc Applications page, create a new application:
- Name: Play blocked message
- Feature Code: *999
- Destination: Announcements (Blocked)
Finally, go back to the Trunks page and change the Custom Dial String to Local/*999@from-internal on the Blocked trunk created earlier. The application can also be tested by dialling *999 from any phone on the system.
