No matter what I do, the VTH remains Offline in the VTO screen.

I can see the images from the VTO, but no notification appears when pressing.

VTO is configured as (Main)SIP server.

VTH is configured as (Main)VTH.

Passwords checked.

The IP range is correct. Performed a factory reset several times, but nothing helps.

Both devices are running the most recent firmware: 4.81.

I read somewhere that it can sometimes take 5-10 minutes for a VTH to come online, but mine remains OFFLINE!

Does anyone know how I can solve this?
