Restore busy signal behavior when Call Waiting is disabled
When Call Waiting is disabled, the expected and previously existing behavior was that incoming callers would hear a busy signal if the user is already on a call.
After a recent update, this behavior has changed. Now, when Call Waiting is disabled, incoming calls are automatically routed to voicemail, and the busy signal is no longer played. This change was made without configuration options and affects all users.
For many organizations, this behavior is not acceptable. Users explicitly disable Call Waiting because they do not want callers to be routed to voicemail or announcements while they are busy. The busy signal is required to clearly indicate that the line is occupied.
Requested improvement:
Please restore the ability to play a busy signal when Call Waiting is disabled, either by:
Reverting to the previous default behavior, or
Providing a configurable option to choose between voicemail routing and busy signal when the user is busy
This functionality is critical for user expectations, call flow transparency, and operational workflows.
