Call of duty is not a game, it’s a religion and you can’t compare this game to classic voip. If your voip is a bit degraded, you will have a delay of few milliseconds and/or weird background noise.
In Call of Duty, a few milliseconds delay means you are dead before even knowing it. Also, competitive ppl there like to DDoS your line just to win. This game is full of cheat and hack to make sure the players will win.
On another hand, you are probably already aware of the 3 NAT types in gaming.
Type 1 (Open): The system is directly connected to the Internet (no router or firewall), and you should have no problems connecting to other PS4 systems.
Type 2 (Moderate): The system is connected through a router properly, and generally you won’t have problems.
Type 3 (Strict): The system is connected through a router without open ports or DMZ setup, and you may have problems related with the connection or voice chat.
You can check your PS4 nat type in the network status.
If you have a Type 1 (Open) NAT you are sure that your game will connect easily with others.
What is your NAT type in your PS4?

Call of Duty seems to be especially problematic.
Not every game are made the same or use the same network engine.
Which games on PS4 are more problematic in your opinion?
Jean
I understand that. But there’s a host of reasons why that night not work - two devices trying to use UPNP behind the same PAT device, an apartment complex or hotel WiFi system, etc.
This isn't rocket science.
Give each customer their own ipv4 IP address and turn on upnp, then they will have open NAT to play their game and host.
I know the solution is always “IPv6”, but I’m curious if anyone here knows why gaming consoles are so stupid when it comes to IPv4?
We have VoIP and video systems that work fine through multiple layers of PAT and NAT. Why do we still have gaming consoles, in 2020, that can’t find their way through a PAT system with STUN or other methods?
It seems like this should be a simple solution, why are we still opening ports or having systems that don’t work?
