    Dahua VTO2000a SIP issue: stops working every time few days after reinstallation

    Hi My vto2000a and VTH worked for long time (with vto as SIP server), but recently I noticed that the VTH did not react anymore when someone pushed the VTO button at the door. The DMSS app still gets the signal, but that is P2P. I could not solve the issue so reset both VTO and VTH and...
