To ensure that only you use your phone numbers, your VoIP devices or software must register with our SIP server, the registrar, using your SIP user name and SIP password.

The registrar differs depending on whether you want to use phone numbers (blocks) or Cloud PBX end devices.

We cover both cases in this article.
