VOIP

Having roaming users be able to use a handset from home, and protect your PABX from brute force attacks and other threats is a great feature of Knocknoc. Users are able to have a handset on their home internet connection, and just login for the day, and their handset will start working.

The steps required will be different for different phone systems, but essentially, you will want to use the script backend to dynamically allow the user's address through your firewall. The firewall on the PABX itself for example with Asterisk or Freeswitch based systems is simple to integrate with using the ipset backend.
