I’m trying to connect a Cisco IP Phone 303 with my Asterisk server but I keep getting Failed(Authenticate) on the phone display.
Here are the configurations I have on the phone. What I suspect the most is under Subscriber information, I’m not sure about what UserID should be, or whether I should add Auth ID:
Change “[coworking]” to “[1001]”. This will allow the appropriate endpoint to be matched, otherwise you will need to experiment with User ID and Auth ID to have separate values.
Try changing the AOR from “[internal]” to “[1001]” as well, along with changing the “aors” value in the endpoint to “1001”. If that fails you’ll need to provide the actual SIP traffic using the “pjsip set logger on” CLI command.
