issues with voice services since moving to AT&T (Teamspeak 3, Curse Voice etc.)

Can anyone help troubleshoot this? I am using ip forwarding to give my beefy router the public IP address and it was from my previous location so all port forwarding is correct, I also forwarded everything in the new AT&T router. It is an arris one for gigabit internet. Connecting to a VPN solves the problem instantly, connecting to any other network like my phone solves the problem instantly, wired, wireless to either router never go through. Could it be from having a 99.x.x.x IP? I'm hoping someone has a solution, thanks!
