Hello, I setup a Grandstream GXP2135 to test out the new phone system. Everything works great; incoming and outgoing calls all work, but having two issues. 1. The phone will randomly start getting a call from it's own extension. For example. shortly after configuring extension 7108 on the phone it started ringing with a call from 7108 (it's own extension) and when picking up, it's silent. Nothing shows in the call logs for this number in the consoles. Happens randomly. 2. In the management console when I find the phone in the Phones section, under MAC Address it shows as "Unprovisioned" and the options for it are grayed out. Not sure if this is related to issue 1 or if this is even an issue at all. Just suspect that this should be showing as provisioned since its working properly. Thank you.
