[Serusers] SER and rtpproxy

[Klaus Darilion]

I can't help you with the cvs version as I never used it (and it will 
cause problems as its under heavy developement). If you don't need 
IPv4-IPv6 translation and separation of rtpproxy from ser, than I 
suggest to use 0.8.12 stable and the corresponding rtpproxy.

ethereal: just sniff all packets without filter. You should see the RTP 
streams sent to the IP address and port numbers in the SDP of INVITE and 
200 OK.

Watch for ICMP errors.
