There are a variety of reasons that calls routed to a Call Group are not delivered to users properly, are delivered out of order, or fail in general. The issue is usually network or configuration related, but in some rare cases can also be carrier related. If there is a carrier issue, calling the Call Group should play the carrier’s error message when dialed.
Verify the Call Group settings in the Nextiva Voice Admin Portal. The two most important factors when troubleshooting Call Groups are the number of rings and the call distribution policy.
From the Nextiva Voice Admin Dashboard, hover over Advanced Routing and select Call Groups.
From the drop-down menu, select the location of the affected Call Group.
Click the Pencil icon to the right of the desired Call Group.
Verify that the Call Distribution Policy is configured to deliver calls in the correct order.
Make sure the Call Group lists the correct Users.
Click Advanced Settings and configure the appropriate number of rings.
If one phone does not ring, but all of the other phones do, disconnect the affected phone from power, and check the connections. Plug the phone back in after 10 seconds and place a test call to the Call Group. If the phone does not ring, dial the phone directly to make a test. If the phone rings, recheck the Call Group settings.
