Ok I trigger a factory reset for both unit and now they are linked !
I can monitor the VTO from the VTH or call the VTO from the VTH (number 8001).
However I still cannot call the VTH from the VTO:
"The number you dialed does not exist"
Both configuration have however 9901#0 as room number. Strange. I'll keep trying.
