Hi Paul and Dale, I just wanted to say thank you for the updates. We haven't got a fully working solution yet so are not completely sure what the fix will be, but your input has helped guide our investigation a lot. On Fri, 26 Jul 2019 at 15:11, Dale R. Worley wrote: > David Cunningham writes

Thank you Paul, and thank you Richard. I must say RFC 6665 4.4.1 does seem to make it clear that the route set in the NOTIFY should be used, and therefore it's incorrect that the re-SUBSCRIBE sends directly to the Contact address rather than using the Record-Routes in the NOTIFY. It's very helpful

Though I notice that RFC 6665 4.4.1 also says: unless the NOTIFY request contains a "Subscription-State" of "terminated." And in our case the subscription state is "terminated". The dialog is then over, so I guess that the other RFCs then apply. On Thu, 25 Jul 2019 at 21:43, David Cunningha

Hi all, Sorry, but I am a bit confused here. I hope someone can clarify things for me. According to RFC 6665 4.4.1 the subscribe dialog (usage) is created when the first NOTIFY request is received by the subscriber and the record-route set (if present) is taken as route set for the dialog:

Hi Paul, I'd just like to check my understanding of your reply. The first SUBSCRIBE is from the UAC sip:113...@es8.example.com, and gets a 200 OK reply from the UAS. It is the 200 OK that should contain the Record-Route header? And would that then oblige the UAC to use that route on all futur
