5.4.5 Configuring Call Number and Group Call
Configure the call number on every VTO, then each VTO device can call the defined room
when you press the call button. On the SIP server, enable the group call function, and when
calling a master VTH, the extension VTH devices receive the call as well.
Enabling or disabling group call function will erase all the added VTH, so you need to perform
this operation before adding VTO and VTH.
Select Local Setting > Basic.
In the Villa Call No. input box, enter the room number you need to call, and then click
Confirm to save. Repeat this operation on every villa VTO web interface.
Log in the web interface of the SIP server, and then select Local Setting > Basic.
Select the Group Call check box, and then click Confirm.
The VTO will reboot, and when calling a master VTH, the extension VTH devices receive
the call as well.
