Solved Grandstream phone continuously receives calls from it's own extension.

I have a Grandstream GXP2170 I just connected to my network. 3cx provisioned it, updated the firmware, and it works, I can make and receive calls. However it continuously also receives calls from it's own extension. This is what is in the call log while it is ringing.

Hmm, never-mind I guess, I manually updated the firmware from 3cx's site and it seems to be working fine now. Strange because i'm pretty sure it did a firmware update automatically when it was provisioned as well.

I think you were on an older firmware version which could not handle CSTA sessions correctly. It was known to make the phone ring, but the latest version should take care of it for anyone else having this issue.
