FreeSWITCH 1.8

FreeSWITCH API commands (FSAPI)

Another very powerful FreeSWITCH concept is the FSAPI. Most API commands are implemented in mod_commands, and almost all other modules add some to the commands that are executable via FSAPI. FSAPI mechanism is very simple-it takes a single string of text as input, which may or may not be parsed, and performs a particular action. The return value is also a string that can be of any size, from a single character up to several pages of text, depending on the function that was called by the input string. One major benefit of FSAPI functions is that a module can use them to call routines in another module without directly linking into the actual compiled code (thus avoiding sudden incompatibilities and crashes). ...
