Hi Rob and Everyone Else,

Are one (or both) ends behind a firewall or ADSL router? If both ends
aren't set up right, it uses a proxy for the communication - a central
point that both ends are able to talk to.

I've tried setting up my connection at home so that it doesn't need
the SIP proxy, but haven't had any success. Has anyone else here
managed to do so? Which ports and protocols should I forward from my
router to my PC? What setting do I (or don't I) set in x-lite? It'd be
nice to have conversations to people in the same city without a 0.5
second lag!

As an aside: If you're chatting to a modem user with x-lite, and
finding it a bit choppy, disable the two G711 (I think it was)
compression thingies, and force it to use GSM... It works and sounds
much better.

Actually... If anyone can recommend a compatible program, other than
x-lite, I'd love to know about it.
