New PBX - on prem or off?

@scottalanmiller said in New PBX - on prem or off?:
PBXs have extremely high uptime requirements.
I will say a lot of businesses claim that they need HA or near HA PBX funcitonality.
But once rational thought and actual math is done, it is rarely actually needed.

I totally disagree with this for most SMB.
It is their 911 requirement.

If his 911 went another path, I'd agree. But his 911 from three sites flows through this one PBX. PBX goes down, 911 goes down.

This is no different than any historical on site PBX. If the phones go down, so does 911.
Policy should be to use cell phone in that case. Much better option today than before cell phones.911 is not a special thing. Phones have always gone out. Phone systems have gone out. Providers have gone out.
Edit to add:
In fact, I know of no municipality that requires 911 be available even if the phone service is down.That doens't mean a business can ignore it. There are codes that require it to be normally available, and as long as it is, and a known plan for a service outage is in place, I know of no other requirements.

What issues might arise in having 100+ phones (building 1 & 2) registering remotely? What type of gateway device might make this better?
One that does not screw with the traffic. Other than that, any solid commercial router should handle it.

The POTS line currently act as fax lines and 911.
There is no need to keep this for 911. You can, but there is no requirement to do so.
As for faxing...... Well you are medical and have abnormal faxing needs.
Assuming that you keep this for faxing and don't mix it with the PBX, there is nothing else to do. The line will go straight from the demarc to the fax machines.
If you want to add it in for 911, then you are adding complexity. You will now need an FXO device to convert it to SIP to connect to the PBX. Obviously if this is a hosted service, you are looping back and forth and it will still fail if the internet is down, PBX is down, etc.

I'm picturing one of these located centrally in the office for 911 usage kept out of the PBX
Edit: Replace "Knit!" with "Emergency"

Are you looking to replace all of your endpoint devices with new VoIP ones?
Well - this is where things get challenging. and I'd want another thread. So give me 30 mins to fix a user issue and make a new thread for this question.
@scottalanmiller if you see this before @Dashrender comes back, fork the quoted post to a new thread.

That's an option.

You've said nothing regarding your on-prem vm capacity/capability?
Also, how is your LAN equipment - good, new, old, POE switches etc?What baring does that have on my question though? How would that affect Onsite or Hosted PBX?
Obviously, if you don't have the ability or capability to "create" vm's...that would kill the on-prem option!
I know I'm being pedantic, but again, it's not really relevant to my question. One could assume that if On-Prem is really the best way - I will make the required purchases to make that happen. Having a VM infrastructure isn't a prereq.
Doesn't work that way. That's not a rational assumption and almost never correct. Having an HA VM infrastructure is almost always a pre-req, not just the ability to run VMs, but the ability to run them at HA. PBXs have extremely high uptime requirements.
So, in reality, this might be the most important factor in deciding this, rather than an "ignore it" factor like you are thinking.
Basically it's the first thing we need to know...
If you HAVE an HA infrastructure, then on premises in an option.
If you don't have one already, the cost of one makes cloud the only option.
As I already know JB said - I completely disagree with you.
You might consider your PBX to be super HA requirements - but clearly most SMBs don't because they don't install them that way.. instead, like my current setup, they have a dedicated device that is the PBX that has zero HA.
Are phones important here? sure, Do they rise to the level of requiring HA - probably not, in fact I'd go so far as to say absolutely not - see recent history for explanation.
And since you're talking about HA - Are you saying you have your PBXs in your hosted solutions all setup as HA? Are the fault tolerate as well? or just fast to get going on another node?

As you know, what SMBs "consider" is irrelevant. Dogs like to eat chocolate. Doesn't make giving it to them smart.

You don't feel that 911 service in three doctors' offices is important?

Well - they would, that would be the plan... But currently that's not the case. The case today is that each PBX has it's own POTS line for 911.

Are they HA as measured in uptime? Yes.
Are they HA in that we can get them back online insanely fast? Yes.
Do we generally run our 911 through them? No.
You do, so you are just using unrelated examples to try to ignore the real issue we are discussing.

Correct - this is our plan today. If the phone system is down, grab the nearest cell phone and call 911.

I know, and so you have a strong form of redundancy both in lines and in equipment, enough to protect you in a law suit.
If you remove all that and just ignore it, you could be personally liable for a 911 problem.

yes, phone CAN go down. But there is "trying to keep them up" and "not bothering to keep them up" that are big factors. And it is a doctors' office, not a normal SMB.

My plan/desire (but can't have emotions here - right?) is to have everything on SIP. I'll need FXO? to convert the SIP lines to analog for the fax machines.
I would like to kill all POTS.
