itself be configured to act as that kind of proxy? Sobolev's media relay for use in the ----- The setup I have is that my Linux server on which SER runs is not firewalled, all UDP ports are directly available as well as standard ports like 5060. My understanding is that PortaSIP will be thus able to open up some kind of voice traffic redirection for each firewalled client to use... Can anyone give me just a bit more explanation on that and tell me how I can integrate PortaSIP with SER. Specifically I'd like to know if I have to use it with nathelper and if so, what's the proper way to do that. Any information collected through this list will be put in a quick HOWTO document for other newbies such as myself :) Thanks a lot, Daniel __________________________________ Do you Yahoo!? Yahoo!
