Hi, It is very difficult to use Freeswitch, because the documentation is very difficult to use. If the documentation was better you would have a lot more users. For example, in https://wiki.freeswitch.org/wiki/Sofia_Configuration_Files , I can read the whole page and I still do not understand fundamental things like: 1) What is a domain? 2) What is a profile? 3) What is a gateway? 4) How is a gateway different than a normal SIP end point? Simple definitions of key ideas and a structured top down descript would help a lot. And there is a lot of useless statements that one has to read through that does not help. For example, "The best thing to do is take a look at these things from a step back." Also it is common to explain what something is not, rather than explaining what it is first.
