1. Tenant domain is a valid domain that resolves to an IP address. Using the domain, the Cisco spa 112 contacts the server with the registration request.
2. The tenant domain is 27 characters.
3. The Cisco spa 112 is using the domain name and not the IP address of the server.

I am only getting 401 answers, no 403s. This is what is confusing me: I am struggling to understand why the device will not send the authentication.

Thank you,
Robert

Check this in this order:

1. tenant domain must resolve to a IP or you must use Proxy settings
in your phone
2. your tenant domain must not exceed 63 characteers (DNS restriction)
3. registar setting on your phone must be using the tenant domain, not the IP


if you only get 401 answers, that means you are not sending the authentication
if you get 403 answers, means you are sending wrong authentication
