thank you very much. just started reading and found

In addition to efficiency, IAX's single static UDP port approach
    makes IAX traffic easy for network managers to shape, prioritize, and
    pass through firewalls.


this is great for microcontroller based application.

While i will certainly look at this code while writing mine, i prefer not 
to blidly include other code in my programs.
