    Retrieve the official files from asterisk.org, extract and change directories. Source: almost 2 years ago
  • SIP server installation
    Perhaps asterisk / FreePBSX or similar would suite your goals? asterisk.org. Bit of a learning curve, but there is lots of documentation and examples too. Source: about 3 years ago
