[Serusers] SER and rtpproxy

[Klaus Darilion]

Use ethereal and watch the packets traversing your proxy. Additionally, 
put log(1,"log messages....."); into your ser.cfg and watch them with:
tail -f /var/log/messages

Put log statements after each condition and watch if the script behaves 
as it should.
