I have slightly modified libosip to prevent continuing
developpement of SIP application compliant to rfc2543 only.

Of course libosip has backward mechanism for handling remote
uncompliant SIP agent but any SIP application based on oSIP
MUST now be compliant with the latest draft. Linphone has to
follow this rule.

Just for recovering the expected behavior of linphone, you
have to patch the file: osipua/src/osipdialog.c so that
linphone always creates a Via header with a "branch" parameter
and also, I have added the latest rfc2543bis-09 "magic cookie".
(which is "z9hG4bK" for obscur reasons :)

This patch is working fine even through a proxy. I'll test it with the
record-routing feature enabled some day.
