I'm concerned about call quality and latency when using VoIP from 7000 miles away from my server. I need advice on whether this setup will be usable given the distance and potential latency issues.
Hi there, My questions are about VoIP in general and internet latency and call quality. So, I will spend some time away across the globe from my self-hosted (FreePBX server). But I still need to accept calls from my clients. I will be in the country that has some internet censorship. I will be using VPN a lot. Moreover, since they block my main protocol WireGuard I will be using nested VPN’s and traveler router. I already set them up and tested them and they work perfectly with VoIP. BUT I’m in the US and latency isn’t an issue. I suspect that I might have troubles with calls from over there due to latency. My home internet connection is pretty fast (uplink where server is), coax \~520/20 Mbps, with average from \~17-26 ms latency, gigabit LAN, business grade network gear. I will be mostly in the hotels with okayish to subpar speeds. According to Google, 50 ms is ideal and 300 ms is not real time communication anymore. I’ve tested my VPN solutions across the country (US east cost), I still get clear voice with no delays. But in my new case it’s almost 3x further! Do you think it will be unusable given distance around 7000 miles from my server? Thanks.
