andre2 Manually. I just went through the configuration process from voip.ms for the OBI200 (https://wiki.voip.ms/article/OBi_100/110_%26_OBi_200) but it’s not complete for the OBI1022. The subaccount is registering, but the button is not correct, and the number is not displayed. If I ever get it going once, I think I’m good to go. The voip.ms article seems complete for disabling Auto Provisioning, which I think was a previous problem, but assigning the subaccount to the button is not properly configured.
Edited: I think I got it. Writing the above response clued me that the Line Keys have to be configured. I found it and configured it. Now it’s working except that it shows the wrong number, which should be a configuration in voip.ms. Thanks for the help.
Edited again to add: The wrong number was in the Phone configuration section. I now know how to configure these things to work with voip.ms.
