Step 1: Try to register your phone with the new configuration. You will probably note an error on your phone registration.

Step 2: The configuration above now uses the module domain.so. Now, to authenticate, the domain has to be inside the domain table in the MySQL database.

To add a domain, use the openserctl utility.

openserctl domain add your-ip-address
openserctl domain add your-domain

Repeat the process for every domain.

Step 3: Try again to register the phone. Now probably the register process will work fine.
