Hi folks,
in draft-ietf-sip-outbound-16 sec 9.1
EP added a Record-Route to SUBSCRIBE
In message #2, EP1 adds the following Record-Route header:
Record-Route:
<sip:[EMAIL PROTECTED];lr>
However, I don't find the text that says EP must do this in this draft.
Initially, it looks like this is mandated in sec 5.3.2, however,
in sec 5.3
<snip>
If the Edge Proxy receives
a request where the edge proxy is the host in the topmost Route
header field value, and the Route header field value contains a flow
token, the proxy MAY need to do additional processing described in
the rest of this section. Otherwise the edge proxy skips the
procedures in this section, removes itself from the Route header
field, and continues processing the request.
</snip>
since there's no Route header in the incoming SUBSCRIBE, so sec 5.3
should not be applied here in this scenario.
Am I missing something?
thanks
Regards,
-Rockson
