I just set up a 3cx server and a couple Grand Stream GXP-2160 Phones. The issue im running into is that the Phones keep getting a call from their extension, Does anyone know how to fix this

Yes, upgrade your firmware: https://www.3cx.com/docs/phone-firmwares/

This was a known issue on much older firmware versions than the one we currently support.
