6.1.3 Group Call
Group call applies to the scene where one VTO corresponds to multiple VTHs.
Please confirm that the following basic settings are correct, and confirm group call conditions
for every connected module.
Please ensure that single call between VTO and VTH works normally. If single call fails,
please check the configuration by reference to “5.1 Debugging Settings”.
Room no. of extension VTH ends up with “-1, -2…” based on room no. of master VTH. For
example, if master VTH is 9901, the extension VTH will be 9901-1, 9901-2…
At WEB interface of VTO, select “System Config > LAN Config”, set “Max Extension Index”
and tick “Group Call” to enable group call function. There is one master VTH at most and
five extension VTHs at most, as shown in Figure 6-5.
