5.4.2 Configuring the VTO Number
Configure the VTH network information. The VTH must be part of the same network segment
as the VTO and the other VTH devices in the system.
You can change the number of a VTO when it is not working as SIP server.
The VTO number can contain 5 numbers at most, and it cannot be the same as any room
number.
Log in the web interface of the VTO, and then the main interface is displayed.
Select Local Setting > Basic.
