[Vadim Lebedev]

First of all what this article:

   - https://superuser.com/questions/1118735/how-are-
   source-ports-determined-and-how-can-i-force-it-to-use-a-specific-port
   <https://superuser.com/questions/1118735/how-are-source-ports-determined-and-how-can-i-force-it-to-use-a-specific-port>

Fails to mention very simple way to force local port number on outgoing tcp
connections:   the bind(...)  call
Second why don't kamalio do not re-use an existing connection to a given
destination is  also interesting question
