Network & Firewall Configuration
If your network uses a firewall that allows access only to certain domains and services, you need to open these in order to use LiveVoice:
TCP: 8088, 8089, 80, 443
UDP Ports: 30000, 30500
Depending on the network/firewall, you might need to open even more UDP ports, but since this is different for every network, we recommend to try it first out by opening all UDP ports.
