psa et al.,
Also.... isn't this a way to get a password & username to use with the relay
server (if your relay doesn't allow arbitrary connections)?
I was told to email Thiago because he may have more info about rtpbridge,
but he has not responded. Thiago, are you around?
Here's my problem... our server guy has said that we have a relay server on
our server because he added the rtpbridge, and he pointed me to the
igniterealtime page ... so now I have to figure out how to use it. I am
currently using (original) LibJingle as my stack, and I don't want to have
to rewrite too much (more than I already have). If the underlying rtpbridge
media relay server handles STUN Allocate messages, and just uses the xmpp
messaging of <rtpbridge/> to sort or "pre-allocate" ports and handout
passwords for them, then I just need to know that, and any other details to
get it to work. If it's something completely different, it would be nice to
know that too.
Sorry to keep going on about this, but we're light on resources, and I'm
just spending way to much time on this right now, with not a lot of success.
Thanks for your patience :-)
