The source code is common for Kamailio and SER, the name of binary being a compile time option. If you download from GIT or tarball, all the sources are included. Packages such as deb or rpm include only selected list of modules.
By default, SIP Express Router (SER) flavour is built when downloading from GIT repository.
If you are using Kamailio flavour, check the download guidelines for sources, deb or rpm packages at:
To take the sources from GIT repository:
git clone --depth 1 git://git.sip-router.org/sip-router sip-router cd sip-router
It checks out by default the master (development) branch.
Switching to latest stable branch 3.3:
git checkout -b 3.3 origin/3.3
Note: starting with branch 3.1, to switch between building SER or Kamailio, you have to use ‘FLAVOUR=ser’ or ‘FLAVOUR=kamailio’ in your ‘make’ command (e.g., ‘make FLAVOUR=kamailio install’).
