</div>There is not really a lot of good conceptual introduction to OpenSER,<br>
although Flavio Goncalves' book ("Building Scalable Telephony<br>
Applications With OpenSER") may be somewhat of aid. The documentation<br>
primarily serves those that already know what they are doing, kind of<br>
like programmers that just need an API reference.<br>
<br>
But basically, it is admittedly a lot of work to figure out an extremely<br>
polymorphic and idiosyncratic environment just to solve a relatively<br>
simple problem.<br>
<br>
I recommend contracting someone to take care of it for you, or stealing<br>
a recipe from somewhere.<br>
