Hi, I have two ATAs - similar to Grandstream 488s, which allows me to convert analogue phones into IP streams. The config server for these devices has options for SIP and NAT/ STUN settings. Can anyone assist me in what I need to do to create a simple point-to-point call, essentially by entering IP addresses manually? The ultimate purpose is so that I can tunnel such connection through ssh tunnel/ forwarded ports. But the first step is to make the (point to point) connection. My machine is Ubuntu. Do I need a SIP server? If so, how can I ensure the RTP stream goes through an ssl forwarded port - ie, how do I ensure the RTP stream goes to a local port, which I then forward using ssh? Thanks in advance Zen
You can't tunnel rtp via ssh because its udp. Is the goal to have a secure connection? OpenVPN can solve that for the most part. Sent from my iPhone On Nov 10, 2007, at 4:35 AM, Zenaan Harkness <zen@freedbms.net> wrote:

I've read that newer versions of ssh have a -w option to do its own kind of VPN. I haven't actually had a chance to try it out though. But like Brian said, normal -L or -R ssh port forwarding is tcp only. --Tim
