I have an Obihai 202 and I am having problems registering it to my SIP provider. I keep getting "Register Failed: 401 Unauthorized". I am able to make outbound calls to my provider, but no incomming. If I keep on refreshing the ObiTalk SIP setup page and eventually it registers, but when I unplug it or make any changes I get the same issue again. Sometimes it will register after several save attempts, but sometimes I have to click save and refresh more than 10 times before it will register.
Through this process I am able to make outbound calls, but not recieve any calls.
Any suggestion on getting the ATA to register all the time?
