Configuration 9
5 Configuration
This chapter introduces how to initialize, connect, and make primary configurations to the VTO
and VTH devices to realize basic functions, including device management, calling, and
monitoring. For more detailed configuration, see the User's Manual.
Configuration Process5.1
Before configuration, check every device and make sure there is no short circuit or open circuit
in the circuits.

TCP/IP informationFigure 5-5
Enter network parameters you planned, and then click Save.Step 2 The VTO will restart.
Make IP address of your PC and VTO IP are in the same network segment.
5.3.4 Selecting SIP Servers
The Session Initiation Protocol (SIP) is used for signaling and controlling multimedia
communication sessions in applications of voice and video calls. ASIP server is an application
provides information or direction to a user agent.
When this VTO or another VTO works as SIP server, select VTO from the Server Type
drop-down list. It applies to a scenario where there is only one building.
When the platform (Express/DSS) works as SIP server, select Express/DSS from the
Server Type drop-down list. It applies to a scenario where there are multiple buildings or
multiple units.
Log in to the web page.Step 1 On the homepage, select Local Setting > Basic.Step 2 The Device Properties interface is displayed. See Figure 5-6.
Device propertiesFigure 5-6
1) Select TCP/IP from the System Type drop-down list.
Default system type is analogue system and shall be changed to TCP/IP.
Otherwise, it will fail to connect VTH.

Configuration 13
2) Click OK to save the settings.
3) Restart the device manually, or wait for auto restart to make the settings effective.
Log in web interface again.
