I wonder if TFTP default bindings are LAN only.
/shrug
It let me connect.
Note: it also does not work on my ZeroTier address.
Now that is weird!

My setup with FreePBX 14 on Vultr.
- There is no firewall on Vultr blocking anything.
- My home network is marked trusted in the FreePBX responsive firewall.
- The
tftpprotocal is allowed in the FreePBX firewall to local connections.
I can connect to from my desktop with
tftpbut I cannot download anything.
Exactly my problem. But I concluded the same thing. Who cares? I do have a small reason to care, but I've got a workaround and moved on to other topics. Thanks for your 2 cents! Glad it wasn't just me.

I like Vultr's stat page.
Here is the network usage of a PBX with ~80 extensions (all pjsip, if that matters) and 15 simultaneous calls at peak.What is the specs of your vultr instance with that usage, ~80 extensions and 15 simultaneous calls at peak.
Also, do you have some formula on how to decide what to get instance base on extension and simultaneous calls ?

Bottom line is that the $5 instance is as small as you can go. You need the 1GB of RAM. If they offered a 900MB option, sure that might work. But the 512MB option will not. So you can't go smaller than the $5 option on the low end, don't try. You'll be swapping and things will get bad, fast, if it will even run.
That said, you could handle hundreds of extensions and way more than 15 calls on that $5 1 vCPU / 1GB RAM option. We use that and we do closer to 30 simultaneous and it doesn't break a sweat. And we don't use g711 either, so we are working it harder than normal users.
You would need a LOT of calls or special usage to make you need a larger VM. We have no customers going larger based on RAM or CPU needs, only on storage needs (we have customers doing huge amount of call recordings or voicemails and just need more space.)

Actually 722 doens't use anything in resources jsut like 711. It is all about being on the same codec for the entire call path.

Also, you can scale an instance to a larger plan if needed.

If you have it on the full path and don't transcode. We don't. We have Opus where we can and G722 where we can't, so we are transcoding regularly.

Yes, good point. Start small and only grow if you measure and find a need later.

Why are you using OPUS?

Adaptable call quality. We notice a huge quality improvement on it. The sound is incredible and when call path degrades it adapts and can hold call quality better than g711 even on flaky connections. We notice a very big overall improvement with it. Plus it uses less bandwidth so offers HQ audio on some pretty tiny connections, but that's a rare need.

That is the point of it, but for most PBX implementations there is no need for it. Sure for people on mobile using unknown signal strengths, but that is still al low over all percent of implementations. I know it is the standard for anything using WebRTC, which I assume SonataSuite does.
Then, what providers support OPUS? Most only support 711 and sometimes 722.

Hence why we transcode to g722 for Skyetel. But the g722 path is from a datacenter to datacenter, so not really worried about questionable call path qualities.
Opus seems to help on everything from wifi to mobile to offices with low quality WANs. We have people on fractional T1 still, so fight some tight bandwidth battles.
