GXP2160 - Phone rings after other phone in ring group picks up.



I’ve got a GXP2160 running version that is in a ring group with 19 other phones. When the main DID is called all phones ring like they should and all phones minus the one in question stop ringing. No other phones on this network are having this issue, any ideas? I ran ping tests to the device with no packet loss but when I log into the gui I keep getting kicked out every 10 to 15 seconds.

Thanks for your help.
