  • You can do this pretty easily using asterisk and then just point your VoIP clients to it’s IP address

    But…

    Whatever you do, unless you’re an expert with network security, don’t leave it on its default port if you’ll expose it to the internet.

    You’ll have that many bots trying to get in that it’ll DDoS you within a few hours of setting it up. Even if you have it on a different port, you’ll have lots of bots trying to get in.

    If you ever see those “unlimited international calls” cards sold in third world countries for like $5-10, those are mostly hacked VoIP systems that have accounts or access to a phone line




  • For a bit of context for those not too familiar with CDN stuff. My web server hosts about 20 small business websites. None are heavy on images or video or anything else. Most sites have well under 1k visitors a day, some are under 100.

    Each month CloudFlare CDN saves me between 40-60gb of traffic which is nothing my server couldn’t handle, but over a year is ~600gb in saved data so it adds up

    If you had a Lemmy instance with even just 100 active users, with all the images and videos and all the federated background communications, that would add up extremely quickly.

    It’s a shitty situation that’s causing mods and users alike a lot of frustration and might be a bit before it’s sorted.

    Unfortunately I think this is something that will need to be dealt with Federation wide before it’s under control… But even then it’ll still add a lot of extra ongoing work to the mods of instances and communities just to clean up anything that gets through
