I have a problem that suddenly there is no notification in my iPhone when someone calls the VTO2211g-WP. I had firmware .511. Then I found the .700 firmware. On some sites it is for the "S" version, but on one dahua site it says that it is the same for mine. Notifications are still not working. I went back to the .511 and did the SCM as well. The notifications worked, but now I can't add the ONVIF user to VTO. The operation failed. I update again to .700 then ONVIF works but notifications do not work! It is very inconvenient to restore to factory settings, because it is not connected by a cable, only wifi and it is inconvenient to take it off and unsolder it to bring it to the house for configuration.. I use p2p.
 
My guess is that going from .511 to .700 has changed the coding in the ONVIF and sadly the camera will need to be reset when you go back to .511 if you want ONVIF to return and the camera to function as it did before you changed it to .700.. Seeing it was working before I am guessing it did anyway.. The best option would be do the downgrade and then Factory Reset the camera to get all the coding back to what it should be running so you can use ONVIF again.

I tried and did a factory reset, in several ways. It's a strange reset - it deletes the IP, password, user, but remembers the tag keys. Basically, the p2p notification works great and never worked like that before - now my phone rings as if DMSS was calling me (looks like a call to my cell phone). Previously, the notification rang so that DMSS would just jump to notification centar or lock display with a strange ringing sound. Then I had to open DMSS and answer it that way.

Small problem 2 - I previously shared vto with another account on an older iPad Air (2?). It doesn't ring there, no notification.
