[Serusers] SER+NAT+RTP PROXY

Fri Jul 9 09:18:35 CEST 2004

Hi all.

I'm a bit confused. Are there then, two media proxys ? "Mediaproxy" and
"rtpproxy", am I right ? In that case, which is a better solution ?

I have been trying SER 0.8.12 nathelper but if fails with "ping_nated_only"
parameter. I guess a I have to use CVS one instead of 0.8.12. Is that right
?

Thanks in advance:

Kiko
