SIP VOIP Question

[Guest]

Archived from groups: comp.dcom.voice-over-ip (More info?)

I'm totally new at VOIP. I thought I would test the technology by
downloading X-Lite from the Free World Dialup site. I got everything
configured, but I'm having mixed results getting things working. I can
sometimes get the test calls (to the 613 number) to work, but not very
often. When I schedule a call using the FWD site, the incoming call does
not arrive.

My computer is located behind a Linksys router. Do I have to change the
configuration in the router to forward any special ports (I thought SIP was
suppose to make things work thru NAT)???

If I do have to forward ports, how do I handle the situation where I have
multiple computer users on my LAN who want to use VOIP?

Thanks,

Yep and nope. SIP has nothing to do with NAT. It is an application
that fails with NAT just like other protocols that carry network info
at the application level.

open port 5060 for signaling and the range of rtp ports for the audio.
which ones and which way depend on who initiates the connection.
You could try stun although I haven't used it. You could also put
your PC outside the firewall just to test before doing anything else.

By the way FWD works well for me with an IP phone outside of my NAT
box.

Good luck.

Try the other softphones that FWD offers. Also, make sure that the
softphone is configured for use behind a NAT (you may need to set up
STUN on the softphone)

Its not automatic. Check the FWD FAQ for using FWD behind a
firewall/router --

Just want to make a correction regarding Adnan's last post. The URL to
LanScape's web site is http://www.lanscapecorp.com

Look for the Global iNet VOIP service logo in the upper right of the
home page and click on it.
