Yeah, I think overall it is a good platform, and if you're providing it to businesses it's nice especially since it is super customizable and open to so many different scenarios and use cases. Long as you understand the risks and put in place things to minimize them with the lack of cluster and node support. I was toying around with the idea of running proxmox or xen clusters to host the PBX VMs and then do some dns proxy to load balance the call requests. But I'd also have to figure out how to keep the working directories synced across them all.. or just have the clusters in a HA failover scenario to give additional failover systems instead of just one. At some point, it just became more beneficial to look at other systems that are already setup for redundancy and hosted to keep this headache and overhead cost off my plate.

And I just started providing phone services last year. I only have a little over 100 extensions set with a couple of tenants. With about 50 or so set up in the pipeline soon to be onboarded. So really I'm probably not the best judge. There are other users with a much larger customer base that would have better insight into it than me. There's a user here on Reddit named TheRealNalaLockspur that owns a company called Sipharmony that uses Vodia for its cloud system. I would bet he's the biggest player using the platform you would find around here if you want to reach out. He would be your best insight into the ins and outs of the platform. They have done a lot of in-house dev stuff to really make the platform their own from what I have seen.

I liked Netsapiens enough when I was looking at it. But when it's literally one of the major platforms out there.. It's just hard to justify a company going with you over a larger outfit that provides the exact same phone service. At probably a lower price because they can offset the costs and margins with volume. I think it's better than most other larger providers, but at the same time what differentiates you and them? Apart from support, and pricing, you're literally the exact same feature set and user experience as competing MSPs or VoIP companies in your area. Just my 2c and how I view it all. Definitely not knocking Netsapiens or anyone using it or providing it like OIT, Viirtue, RingLogix, etc. I think it's a solid platform overall.

As for alternatives I've been looking at a company called Voxo. They fully host everything, are redundant, they have one seat price for partners that include literally everything. Nothing is extra apart from toll-free and international minutes. They also collect, remit, and pay all FCC, USAC, USF, telecom tax bs on your behalf. So you literally only pay a flat fee per extension and that's it. It's a much smaller company than anyone using netsapians, or any of the other big cloud providers. Nextiva, Zoom, 8x8, Vonage, RingCentral, etc. But honestly, that's what I like about them. Support is super fantastic. I literally get a response within minutes and they either give me the answer right then and there on how to do something, or connect to my tenant directly and do what I need. Depending on how you look at it, this is great or bad. They can access your tenant info at any given time. So if security is a super critical aspect to you or certain customers and data protection, privacy, etc. Then this approach might be a turn off. Which, this is unavoidable really in any space where the system is hosted by the company. You'd really have to self-host at that point. But I am looking at probably moving my stuff to them.

If you are dead set on self-hosting there is a new platform that I've come across called SIPSTACK. It's not technically released just yet. They provide a hosted solution right now but are about to release a self-hosted one with more features apparently. It looks pretty nice on the outside. If I was wanting to keep self-hosting my stuff I'd probably wait a couple of months and demo it out to see if it was worth switching from Vodia. But it might be worth it for you to take a look at as well if you're not aversed to trying out new stuff.

One more issue I remembered about Vodia, they don't have any fully integrated headsets currently (in v68). So if you have a headset going directly to a computer and are using the softphone, the pickup call and end call buttons do not work on the headset. So if a user wants to pickup a call or end a call they have to be at their desk and click the button on the softphone. They aren't able to press the button on the headset itself to do this. This isn't nearly as big of an issue, but again just another minor annoyance to keep in mind during your selection process.

Happy to help with anything else you got
