[Serusers] rtpproxy usage??

[szj]

   It's greate that rtpproxy support multiple stream. Thanks
Maxim for his great work.
   Now I want to test the rtpprxy+SER, But after starting the
rtpproxy, I can't find which ports the rtpproxy listens.
I don't understand the arguments of rtpproxy all well.
Is it a must the rtpproxy runs on machine with  multiple network
adapters?? How to start it with the appropriate arguments?

  Thanks for your kind help and advance.

   Best Regards.
