If you want to use cContact on your Wi-fi at the Office please read the requirements for your network. To use video calling on your Wi-fi your network must allow communication with the following ports in your firewall:


Port Protocol
80 TCP
443 TLS
443 TCP
5004 UDP
5004 TCP
33434 TCP

Important: check on every location of your company if Wi-fi is enabled for video calling.


cContact does not work in a virtual environment like Citrix or a Terminal-server. Use a desktop or laptop that is not connected to a virtual environment.

Netwerk Test

To check if your Wi-fi is ready for video calling run the Network Test on a desktop or laptop.
