What is the IP whitelist feature and what does it do?
The IP whitelist feature is a security oriented tool which allows users to configure IP addresses from which they want to allow SIP registrations. By entering IP addresses the user will be preventing any IP not listed from registering any UA to the account. Registrations will be accepted only from the IP addresses listed.

This feature does not prevent login to your My Callcentric account based on IP.
This feature does prevent SIP registrations to your account based on IP.
This feature is meant for advanced users who use static IP addresses.

You should not use this feature:

  • If you use a dynamic IP or dynamic hostname
  • If you use a mobile softphone
  • If you register your UA from multiple locations

Enabling this feature with no IP addresses in the list will prevent ALL registrations to your account, even your own registration.
