Device worked great until tonight. I received a call and the device lost its sip connections. I unplugged it and it connected again. Made a test outgoing call and that was fine. Made a couple test incoming calls and both failed. The phone would ring but it was dead air on this end followed by a busy tone. Submitted a ticket (Ticket ID: RSE-677109 ) and continued trying. Managed to receive two calls and then the device lost connection again and has not reconnected.

Waiting on support to reply before I reset it again.
