Hi, Any ideas what this obscure message means ?   sofia.c:3901 ERROR: unsupported transport.  It shows up when running a "sofia profile external rescan" (and originating calls doesn't work either). My provider sip_profile was copied over from a known good other machine. So I don't know what sofia is complaining about ? <include>         <gateway name="foobar">            <param name="auth-username" value="none"/>            <param name="password" value="none"/>            <param name="extension" value="default"/>            <param name="proxy" value="foobar.example.com"/>            <param name="expire-seconds" value="300"/>            <param name="register" value="false" />            <param name="register-transport" value="tls"/>            <param name="ping" value="false" />          </gateway> </include>
