Good Day!
I'm using 3CX in both of my buildings, each building has a different ISP, thus I have VPN between the two. The edge device at my main building is a 2600 and the edge device at the remote site is a TZ-215W. I already have VPN set up and I can connect to resources at the other site respectively, but what I find is when I make calls in between the buildings, is occasionally during the day the voice call will be very choppy. What would you recommend to adjust VPN or QOS on VPN (is there such a thing?) for that matter so that voice calls will always get top priority over all other traffic?
Thanks,
