I tried it but it didn't worked. When I use "proxy server", the INIVITE
is sent to the proxy (same ip as registrar) and a "Route" header is
inserted. --> doesn't work with iptel server.
When I use "outbound proxy", there is no "route" header, but the request
is not sent to proxy but directly to the callee.

What is it good for to have a "pre-route set" when the server in the
route header is the same as the one to which the invite is sent? If I
want my INIVITE to be sent via a certain proxy but I have to use an
outbound proxy first, a route header looks reasonable to me. But in the
case of linphone the proxy in the route header is the same as the
outbound proxy. Maybe this confuses the iptel proxy?

I also don't understand the various proxy settings in linphone:
What is the difference between the "outbound proxy", "redirect proxy"
and "proxy server" setting in detail (linphone 0.9.1)?
And what are the changes in linphone 0.10.0 where there is only the "Use
this registrar as outbound proxy" option.

Furthermore, a scenario where the registrar server is not the same as
the outbound proxy can' be solved. Wouldn't it be better to allow to
different servers?

Thank you for your answers,
