Wireguard seems to work fine for almost everything. It connects. The problem is I am losing VOIP connections after 15 minutes when something is timing out. Wireguard does not drop during this time, but the VOIP connection does, and the VOIP company is saying I need to unblock certain ports.
The VOIP company said to keep certain ports open.
I do not know if I need to do this inside my computer’s filewall or if I need to go into Luci or GL.inet’s menu and manually open up ports. I also don’t know if opening up ports generally makes me more open to being hacked.
Should I be using Luci or Gl.inet’s interface? How should I do this?
I suggest asking the VoIP company whether they support SIP encryption with TLS and/or SRTP, which are now supported by many providers. If so, then calls will be secure and more stable than going through a WireGuard/VPN router. Many softphones also support TLS and SRTP.
I have VoIP running over SIP TLS on a Grandstream ATA that works well.
I do not work for and I do not have formal association with GL.iNet
