If the VPS is only answering calls not answered by user extensions:
Go to the 3.CO - 2.Incoming / Outgoing screen. Program lines to ring user extensions immediately
for all time modes. To give users time to answer the call before the VPS picks up, we recommend
setting the delay to a few seconds for each extension connected to the VPS. Set a different delay time
for each extension connected to the VPS. Finally, go to the 3.CO - 1.Line Mode screen and set all
trunk (CO line) types to Normal. Click Apply to save the changed data.
