public string[] addressable_vcard_fields { get; }
A non-%NULL GStrv of vCard fields supported by this protocol.
If this protocol does not support addressing contacts by a vCard field, the list is empty.
For instance, a SIP connection manager that supports calling contacts by SIP URI (vCard field SIP) or telephone number (vCard field TEL) might have { "sip", "tel", NULL }.
