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.

You should enable this feature:

  • If you use an IP PBX with a static IP
  • If you have a static IP
  • If you will keep track of the IP addresses you use

If you are not sure of whether to use this feature then please open a trouble ticket on your account so that we may explain whether or not this feature will work for you.
