Sorry for the cross-posting of yesterday :P

Hello folks

I'm having troubles with GM-Opal when trying to receive SIP calls.
I initiate SIP calls to the outside, but I can't receive INVITE.



That should belong to gnomemeeting-devel as GnomeMeeting SIP is not a
stable product yet.


I suspect that my host is behind a firewall, though I'm not sure this is the problem.


You have a public IP.
I mean I don't know if some of my ports are blocked by the firewall of the office...


I've tried three different SIP clients: GM, X-lite (closed src), and Kphone. Oddly, X-lite and Kphone can both initiate and receive SIP calls without any problems.



So your problem is that :
- you can initiate calls
- you can not receive incoming calls

Is that right?

Well, it seems that GM cannot receive incoming calls while other clients can. I wonder if this comes from the way I've configured GM or of this is related to the connection mechanism (you know, the port 5061 stuff)


As you can see, for GM no INVITE message ever reached my host (vis156b)


I can not see that :)

Have you looked with ethereal to see if your host actually receives a
message or not?

Oh sorry !
I've checked with ethereal as you said, and it is now obvious that Xlite uses STUN somewhere, so this is probably why I can receive incoming calls with it. I've also tried running GM with STUN support enabled in the prefs, but it didn't make any difference. My host doesn't receive the invite message.
Please find to ethereal logs attached (xlite, GM-with-stun, GM-without-stun)


I suspect this is because GM seems to negociate the connection with the server differently than other client (see the name of the port tcpdump'd : sip-tls instead of sip)



It just has a source port of 5061. But the PDUs all contain 5060 in the
Contact field, so that's where they should contact you.

ok I believe you...


Does anybody can light my candle ? Can I compile OPAL differently so that GM tries to connect through the sip port (5060) instead of sip-tls (5061?) ?


Currently not. But if it is the problem, then it is on their side.

We see GM doesn't receive an INVITE, but does the host receive an INVITE
at all?
nop (see attached logs).

Also, when are your opal/gnomemeeting versions from?

You need to apt-get install evolution-data-server
Actually I had some troubles with evo and my ubuntu :P

See the answer arrives on port 5061 (if=...), that means that even IF
the INVITE was sent on port 5061, it would reach you.

It seems no INVITE is sent at all.

OK

OR :
"Discovered Restricted Firewall"

can be the problem. Is that firewall on your machine?

starting GM with STUN support enabled and -d=6 reports that I'm behind a symetric firewall. However, it also reports that it cannot create a socket (see attached log). Can this be the source of my troubles ?
