When you create a Ringotel organization, you specify a domain that must be unique across all Ringotel organizations. This could be something like "mycompany" or "mycompany.com". Ringotel users will need to enter their organization's domain when logging into the Ringotel app.
Users will then connect to the following server from their devices: <domain>.ringotel.co:443. Therefore, this address or the corresponding Ringotel IP addresses should be allowed, not blocked, on the user's network.
Where to find organisation domain?
Once you have created an organization, you can find its domain under its name in the list of all organizations created in your Ringotel account. In the example below, the organization domain is "abcdcompany".
Is it possible to change organisation domain?
At the moment, it is not possible to change organisation domain, once it is created.
