Whatsapp voice calls are not working thru firewall

Hello Community,

I would like to see if anyone had any success with making Whatsapp calls and/or video to work using an internal wifi network.
When I try to make a call with my cell phone, I will see "ringing..." and hear the phone ringing. The receiving side will pick up, but my side will still just see "ringing." After about 10 seconds, the call fails. For a testing policy, I've allowed ANY to ANY traffic , no filtering of any kind. I chose the application, whatsapp-base, whatsapp-web, whatsapp-video, and I also allowed:

TCP 80, 443, 4244, 5222, 5223, 5228,50318, 59234 & 5242

UDP Ports: 3478, 45395, 50318, 59234

I did a packet capture as well, but couldn't see any drop packets.
Appreciate any feedback.

Thank you!

@mrkenkenit,

Check and see if you have any denied traffic trying to hit the NAT source address.

Hi BPry,

Thank you for the suggestion. Would I be able to see this in the already captured pcap files or this has to be done with a live session? What exactly should I look for?

Thank you
