Sounds like a firewall problem, but you haven't given much detail of
your situation. Getting SIP through firewalls can be tricky and there
are many things that can go wrong. There are multiple ports used by SIP
for setting up the call, and RTP for passing the audio /video data, and
they are variable. A comprehensive answer would be huge, so here are
some pointers for further reading.
The most common solution is to use STUN, but in some situations (like
mine) it's unreliable. I can't give you any pointers on that as it
doesn't work for me.
If you have control of your firewall I suggest using an outbound proxy
such as siproxd since this makes life much simpler, especially as you
have multiple clients behind the firewall. Siproxd has config examples
for running it both on and behind the firewall, depending on what suits
your situation. This includes which ports will need forwarding and where
to. I haven't had a problem since I installed this. Outbound proxies are
increasingly appearing on ADSL routers, so if that's what you're using
t might be worth checking the manual.
If you don't have control of the firewall then you'll have to speak
nicely to firewall admin ;-) Good luck!

Dear All,
I have installed linphone-3.0.0 release with plugins in 2 linux x-86
machine's running fedora core 8 release.
i created 2 sip accounts in sip.antisip.com <http://sip.antisip.com/>.
firstly, in lan , i tested linphone using this setup,
user a -> sip:[email protected] <mailto:sip%[email protected]>
user b -> sip:[email protected] <mailto:sip%[email protected]>
it worked, voice is working. video not tried.
now i tried to test in my real network,
i am in a private network behind a firewall/gateway which is connected
to internet.
in this test, the sip registration itself failed.
in linphone debug, no response from sip.antisip.com
<http://sip.antisip.com> timed out came.
in my terminal, if i try to ping sip.antisip.com
<http://sip.antisip.com>, it will resolve but will not ping as the
firewall/gateway is in place.
guys help me in sorting out this.
