Specifically, if the Path: header is missing from the
REGISTER request or
the first Path: does not contain the ;ob URI parameter:
1) If the REGISTER contains a Supported: header with the outbound option
tag and the Contact-URI contains a reg-id parameter the registrar must
reject the REGISTER with 439 First Hop Lacks Outbound Support.
2) If the REGISTER does not contain a Supported: header with the outbound
option tag then the reg-id parameter must be ignored.
the above applies only if the registrar is not the first hop, i.e., if
via header indicates that there was a proxy between the ua and
registrar.
