Does the BT110 work in an environment where the voice network is isolated from the data network?

The BT110 supports dual-homed mode, allowing voice and data networks to be separated.  It uses its two network interfaces, Ethernet interface and Wi-Fi interface, to connect to these two isolated networks. You can configure the BT110 to have a dual-homed network configuration with Wi-Fi I/F ↔ data network and Ethernet ↔ voice network or Wi-Fi I/F ↔ voice network and Ethernet ↔ data network.  

Note:

1. Before starting to configure the dual-homed mode network interface, please confirm that the VoIP network DNS server(s) (i.e. the DNS server(s) resolving VoIP proxy/server FQDNs) is(are) reachable from the BT110 device’s voice network.
2. The IP address announced by BT110 device IVR (either by pressing the Flash button for 3 seconds or dialing “***1” on the POTS phone connected to the FXS port of the BT110 device) is the IP address of the data network when the BT110 unit is configured in a dual-homed mode.
3. The companion Mobile App and the Tablet Controller need to be configured to access to the BT110 device’s data network to communicate with the BT110 device as well as the BuddyTalk network server. 

To configure the BT device for the dual-homed network configuration, navigate to Network > Dual Homed.  You can enable the Dual-Homed mode, and choose between Data/Voice IF to be WiFi/Ethernet or Ethernet/WiFi. The provisioning server is by default assumed to be accessible via the data network.  If the provisioning process needs to be conducted from the voice network, then, check the Porv Bind with Voice IF box.
