Well I can tell you that any SIP program can do this, one that comes to mind is Linphone. But you do need a provider. Almost all providers deal with UDP. You might be able to find one that transmits over tcp but that’ll be a very small list. TCP isn’t reliable for VoIP, for media anyway. At best you’ll find one that encrypts the signaling over TLS, which is TCP. But audio, even if encrypted too, is done over UDP.... Source: over 1 year ago

Similarly, you can use any SIP (VoIP) provider (e.g. VOIPo Cloud), and configure the SIP account details in your native phone app. This way you will also be able to use a SIP softphone on your computer (e.g. LinPhone on Linux or Telephone on Mac), or even a real SIP phone in your home. Depending on your SIP plan you may or may not be able to make international calls this way. Source: over 2 years ago

People will follow you on Twitter or join your Discord server (I created ours today, come join us!). Being hyper-focussed on a single project risks missing the forest for the trees. Success then brings its own challenges: there's a lot of activity, too much to guarantee... - Source: dev.to / over 1 year ago

HACK: If you want to save all of your current slack messages, sign up for https://orbit.love, connect it to slack, and then grab the messages from the API. Not sure how much longer this will work, it takes time and they may catch on. I do like Orbit as a user, still a relatively new product. - Source: Hacker News / almost 2 years ago
