Bug#783853: outgoing call without using proxy

[Daniel Pocock]

Package: linphone
Version: 3.6.1-2.4+b1
Severity: important

I set up one SIP account in linphone, my pocock at debian.org account using
the debian.org SIP service.

It registers successfully.

It can receive a call from a sip5060.net (Lumicall) user

If I try to make an outgoing call, with the pocock at debian.org account
selected as "My current identity", the call fails with the error "Mutual
TLS required to handle that message"

This error comes from the sip5060.net SIP proxy.  It is complaining
because linphone made the outgoing call by sending the INVITE directly
to the sip5060.net proxy, instead of sending the INVITE to the proxy for
debian.org

Workaround: in the account settings, there is a field called "Route", if
I put "debian.org" in that box it sends the INVITE via the proxy.  It is
probably better if that is default behavior.
