   For example, some devices will use locally-configured
   explicit loose routing to reach a next-hop proxy, and others will use
   a default outbound-proxy routing rule.  However, for the result to
   function, the combination MUST provide valid routing in the local
   environment.  In general, the service route set is appended to any

   Systems designers must match the service routing policy of their
   nodes with the basic SIP routing policy in order to get a workable
