Hi, this is the result of my dialog with our SIP support guys.
Apparently, linphone gets confused and offers my internal LAN address
(192.168.1.*) instead of VPN one. The result is that it the registration
to the internal SIP server fails (Not Found) and when calling the
contact inside of RH VPN I get "Service Unavailable". It doesn't matter
whether I use an internal STUN server or use my IP address directly
(this VPN connection is not NATed).
This is the only showstopper for using linphone as my main SIP client
(the only other working SIP client for me is Twinkle, and I really don't
like KDE apps on my machine). There are some other problems (e.g., for
many users STUN/direct IP/etc. setting should be per-account, not
per-program preference, many UI glitches), but fortunately non other is
a showstopper for me.
What do you think?
Matěj

Hi Matej, is it possible to get a tcpdump from your machine from when
you start Linphone through to attempting a call? The txt file doesn't
give me the depth of information I'd like to have in order to analyze
this.
Is this what you want?

Matej, many thanks for capturing this, the dump is quite helpful.
I have extracted only the packets relevant to your client attempt to
register to and call from our internal systems - this file is attached.
In short, the dialog begins between your client, 10.36.4.214 on vpn, and
our registrar, 10.32.8.32, at Packet #75.
The client sends the REGISTER request, but the client SIP stack is
setting your Via: and Contact: address to 192.168.1.2:5060. This is the
core problem, obviously 192. is neither valid nor routable.
Linphone's exosip stack should set your request IP's to the vpn IP, not
to the un-NAT-ed IP of your machine.
Please let me know if you need more detail or would like to do more
troubleshooting.
