We had this fun and excitement once we finally cut-over to our VoIP system. ALL our phones were doing this.
I believe we selected all the 8-character entries and yanked their leases. This part might not have been necessary, but we also reset the DHCP Server service. Once the DHCP Server service was back up, we re-booted all the devices. Don't know what caused it, but that fixed it (for now, anyway). -- Richard D.
