UCM6202 - GXP2170 phones all POE Latest firmware
Very random like once every couple of weeks.
Call comes in through SIP provider to the main ring group.
When Users pick up the phone to answer the call other random phones start ringing indefinitely until the user walks over to the phone to pick it up. Sometimes it doesn’t happen until the user parks the call. When this happens there is nothing on the display showing the number coming in, it just shows that the lines are ringing.
Also when the user picks up the phantom ring and listens to the handset. All they hear is ringing in the handset.
They have to walk around to each random phone and pick it up and hangup to make the phones stop ringing.
Remote users on the system are not getting the phantom Rings.
Appreciate your input.
