It should say:

   NOTIFY sip:app.example.com SIP/2.0
   Via: SIP/2.0/UDP server19.example.com;branch=z9hG4bKnasaii
   From: sip:joe@example.com;tag=xyzygg

   Call-ID: 9987@app.example.com
   CSeq: 1288 NOTIFY
   Contact: sip:server19.example.com
   Event: reg
   Subscription-State:active;expires=3600
   Max-Forwards: 70
   Content-Type: application/reginfo+xml
   Content-Length: ...

   Event: reg
   Subscription-State:active;expires=3000

Notes:

The two NOTIFY examples are missing mandatory Subscription-State header.
