1416 1416 cheikhdtn (TechnicalUser) (OP) 25 Nov 21 09:44 HI We have IPO 500 v2 9.1, phone 1416 reboots on its own, I changed the phone still the same problem. Thanks RE: 1416 snowman50 (TechnicalUser) 25 Nov 21 10:29 Bad connection Cable issue Floor point / socket issue port issue. Try moving to a different port on switch Change cable between phone and outlet.. Firmware issue IP address conflict. Ignore this as it is digital RE: 1416 tac84 (Programmer) 25 Nov 21 10:34 Just to clarify, you're definitely talking about the 1416 Digital handset? Not the almost identical 1616 or 1616L IP handset? Thanks, Tim Adelaide, Australia RE: 1416 cheikhdtn (TechnicalUser) (OP) 25 Nov 21 10:46 I connected phone digital 1416 directly to the port of the card combo module, still the same problem. RE: 1416 snowman50 (TechnicalUser) 25 Nov 21 14:07 Did you change the cable from the phone to the port. Try the phone on another port to rule out the port position. RE: 1416 cheikhdtn (TechnicalUser) (OP) 25 Nov 21 14:14 I changed the phone cable same problem when I plugged in another port(combo card) the phone works fine. RE: 1416 budbyrd (Vendor) 25 Nov 21 17:44 Sounds like a bad port. Three thing go wrong with phones. Endpoint. Cable. Or port. If directly connected and it is a problem it is the port.
