WhatsApp voice calls firewall ports

12 08 2015

Trials and errors given me following list of ports to be open in guest wi-fi firewall in order for WhatsApp calls to work.

Until then it was giving error “Call couldn’t be placed due to wi-fi network that prevents WhatsApp calls”.

TCP: 4244,5222,5223,5228,5242

UDP: 3478,45395
