Therefore, an UAC compliant with RFC 6665 will ignore
the Record-Route
headers in the SUBSCRIBE 200 and will wait for the first NOTIFY to get
the Record-Route headers and set them as the route set of the dialog.
If such a NOTIFY does not contain RR then the UAC will fail to create
the route set and the next re-SUBSCRIBE will miss them.
So in short: every proxy in the path of a subscription MUST add RR to
in-dialog NOTIFY requests, and thus Kamailio default script file
should perform record_route() for in-dialog NOTIFY requests.
inaki,
your summary is not correct. it is enough to add rr header to the FIRST
notify after dialog creating subscribe.
would it be difficult for kamailio presence server to somehow (in a
header) indicate that the notify is the first one?
