切断検出

When outside calls are not properly disconnected by trixbox Pro , it is possible that your telco is not providing "Disconnect Supervision" as part of your service.

Are you experiencing any of the following?

1. When a call comes into a queue and is abandoned (caller hangs up) the call stays in the queue until it is picked up, but there is no one on the line.
2. When someone outside your office drops off of a conference call the line is not released.

If you experience either of the above and you are using a PSTN (or POTS) line, you may not have "Disconnect Supervision".

Follow these instructions to determine if your POTS lines have Disconnect Supervision:

1. Call into trixbox Pro from an external phone. Your cell phone is fine
2. Dial an extension
3. Pick up the extension by pressing the speakerphone button
4. Hang up the *cell phone*
5. Did your extension auto-hang up or play a tone after hanging up the cell phone?
