Asterisk is not sending a Decline message back to the caller.
- Peer A calls Peer B.
- Peer B declines the call.
- Asterisk acknowledges the decline but no Decline message is sent back to Peer A.
- Peer A still displays Ringing for approximately 8 seconds before call ends.
- Asterisk’s log shows a Forbidden message.
How do I get Asterisk to send a Decline message back to caller so it may end call immediately?
