From looking at the source code I believe to authenticate against a
realm you have to configure it manually in the linphonerc file under
section [proxy] as that setting is not exposed through the GUI.  The
file should be at
"C:\Users\<UserName>\AppData\Local\linphone\linphonerc".  The
recognized configuration keys for that section are (default values in
parentheses):

    avpf
    avpf_rr_interval (5)
    conference_factory_uri
    contact_parameters
    contact_uri_parameters
    depends_on
    dial_escape_plus (0)
    dial_prefix
    idkey
    nat_policy_ref
    privacy
    publish (0)
    publish_expires (-1)
    push_notification_allowed (0)
    quality_reporting_collector
    quality_reporting_enabled (0)
    quality_reporting_interval (0)
    realm
    refkey
    reg_expires (3600)
    reg_identity
    reg_proxy
    reg_route
    reg_sendregister (1)

In reg_proxy you have to use the (resolvable) hostname of the proxy
and in realm the unresolvable realm name.  At least that's my
understanding.
