Call Home Discussion (Alberto, Kent leading)

  *   Three options were discussed
     *   Assign a port application
     *   Add new RPC saying why the call is being made
     *   Use call home to establish session. Then start a dynamic subscription.
  *   Conclusion

     *   Select Option (i.) Assign a port number for NETCONF & Restconf call home to receive connection
     *   Applications agree on port number so that IANA integration isn't needed.
     *   Leaf ref points to draft-ietf-netconf-netconf-client-server
     *   Alberto to make needed changes to the draft.
     *   Note: Restconf Call home only needed for Dynamic Subscriptions when a Network Element based Publisher wants to initiate establishment of the Secure path. This is not needed for Configured Subscriptions over HTTP2.

Call Home Error Message Discussions (Tim)

  *   Useful material provided on Error conditions
  *   Some of the proposed mechanisms were discussed as part of call home (e.g., exponential backoff). Not all of these need to be standardized.
  *   Tim to work with Kent on draft-ietf-netconf-netconf-client-server to see what is relevant to incorporate.

New draft Restconf & HTTP2 - Comments, thoughts, & open issues (Eric)

  *   Michael's comments will be embedded, and the new draft posted this week.

What needs updating for v04 of YANG Push (Eric)

  *   Reviewed accumulated changes which need to be made to current version.
  *   Eric/Alex to make these changes and post to Git Repository
  *   Balazs to add text what should be on on-change subscribable
