I installed Bt versatility firmware before and it is quite obsolete now which I think needs some new upgrade somehow to keep it working efficiently. Any links that have the updated bt versatility firmware?
Searching for new and updated Bt versatility firmware
I am not familiar with BT Versatility but I managed to find a site that describes a work around to the same problem you have. The solution that the user found was to use a plug-in on Mozilla Firefox which shows hidden fields on the configuration site.
Open your Mozilla Firefox then go to Tools, then Add On. Next, search for “Unhide fields” and then install it. Restart Mozilla Firefox if it is required. Once it is loaded, use Mozilla Firefox to navigate to the web config site and then select VoIP which is found at the left side.
After that, choose Change Advanced VoIP Setting located at the bottom. On that same screen, right-click anywhere and then choose Show Hidden Fields. After this, this will allow you to permanently change the proxy and user domain as if by magic.
