Setting line type default to 5061/TLS

Where can I change the line provisioning globally so that 5061/TLS is used?
In Default Settings we have "line_sip_port", that can easily be set to 5061.
But line_sip_transport is "tcp" and looking at account.X.sip_server.Y.transport_type, the valid values are 0 - 3, so how do these interact?
