Disconnect Supervision for Vega50/5000

Problem

In a scenario when in the inbound call : Legacy PBX > Vega > Asterisk - The PBX side initiates the disconnect, but Vega doesn't disconnect.

Solution

The problem that can be here is that the PBX is sending a disconnection tone (frequency,time) that Vega is not configured for.
These are the 3 steps for troubleshooting:

1. Polarity Reversal - The first step will be to try enabling Polarity Reversal option.
   In the WebGUI please navigate to: Expert Config > POTS > FXO Port Hardware Profiles > Line Reversal - mark it as ON
   Apply + Save + Test
   Note: This may not work outside of the UK

2. Loop Current - If step 1 didn't work for you, then you can try to change the Loop Current
   In the WebGUI please navigate to: Expert Config > POTS > FXO Port Hardware Profiles > Loop Current Detect change from 0 to 300 or/and 500
   Apply + Save + Test

3. Tone Detection - If the above two methods didn't work for you, then you can try to adjust the Tones.
   In the WebGUI please navigate to: Expert Config > Tones > Tone Detection > Mark Enabled
   Apply + Save + Test
