What you need to build JsSIP

You just need to have Node.js/npm and git installed.

NOTE: npm comes with node now.

How to build JsSIP

Clone a copy of the main JsSIP git repo by running:

git clone https://github.com/versatica/JsSIP.git

Enter the directory and install the Node dependencies:

cd JsSIP && npm install

Make sure you have grunt installed by testing:

grunt -version

Finally, to get a complete version of JsSIP, type the following:

grunt

The built version of JsSIP will be available in the dist/ subdirectory in both flavors: normal and minified. Both linted (with JSHint).
