There's no need to run your own PBX to hit all those bullet points. Many voip providers do most or all of those things nowadays. I do them all with my voip.ms extensions. Audio and lag, though, can sometimes be on you to figure out, as it's often your own network or device that is the problem.
I have been using softphones on android for many years, and nowadays, I think Groundwire is more than worth paying for. It has been working flawlessly for me, including SMS messaging. I also use a grandstream ata and a set of grandstream DECT phones. They have some very powerful PBX-like features built right into them. Try a couple of voip providers to see which ones you like to work with. You also don't *need* to use the same company for incoming DID, outgoing calls, and "internal" extensions. As long as your providers are open, you can mix and match if you want. It's tough to beat voip.ms for price, and while they are very DIY, they provide a lot of functionality.
Thank you, great information. I had not looked at voip.ms before. The service suite looks pretty complete for VoIP. And I had not considered an ATA and some DECT phones but I like the idea.
One aspect I *really* like is that secure SIP transport is available. My current provider only allows UDP which is inherently less secure that using TLS. The DIY aspect doesn't bother me too much since my current provider is very much that way. Based on your intel, I think I will give voip.ms a try and see how that goes. I have a third line available on my Cisco SPA303 I can use to test it.
My learning curve is steep but it feels like I've cracked open the door by setting up a SIP account, getting a DID phone number, and making sure the provisioning all works.
