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>
