Solved difference between IP PBX and IP Centrex

sorry guys for my English, sometimes i can't fully understand the answers, so Hosted IP PBX is a private thing owned by the costumer meaning that the ISP just hosting it,
In theory, but I've never heard of an ISP hosting an IP PBX. ISPs just don't do that, there is no incentive for that. ISPs always do IP Centrex.

This is why @NTG sometimes refers to their hosted PBX product as "true hosted pbx", because it is not a shared service, can be taken on premises by the customer and is owned by the customer. It is not a Centrex. I don't know of any other "Hosted PBX" vendor that actually does hosted PBX and not IP Centrex.
to be honnest i get confused about this, is there any differance between hosted IP PBX and IP centrex ?? i think it is the same thing
If I'm understanding this correctly, a PBX only has extensions, etc for your company on it. A Centrix has many customers extensions on it.
While that is effectively true, that's not the factor that causes one to be one and one to be the other. No one actually makes a Centrex system for only one customer (although on day one, in theory, they might only have one signed up until the second customer comes along.) PBXs are almost never shared, but we certainly have PBX customers who put multiple companies on a single PBX.

yeah exactly, this is what confused be, because i didn't see any benefit for the ISP to host your IP PBX
thanks -

IP Centrex would be owned by the phone provider. No necessary connection to the ISP. I realize that in your country the ISP, phone provider, Centrex provider and many other functions are the same company and are actually the government so this gets blurry for you. But as IT terms go, ISP is not in use here.

thanksIt would be beneficial TO YOU, but not TO THEM so they won't provide it.

This is why Elastix was moving away from the PBX model to the multi-tenant model. The core FreePBX based Asterisk system they had was never designed for multi-tenancy and people really wanted it. So many people outside the US use Elastix in this way and over come the shortcomings with various hacks and changes.
I blame Elastix for the abandonment of the one model without anything solid working. I am sure it all comes down to money though. Elastix is owned by PaloAlto and they are a business. Business exist to earn money.

yeah you are right it is All in one

In the US, and in most of the world, your phone company, ISP, Centrex providers, PBX providers, power company, etc. are all independent of each other so there is a lot more flexibility.

yeah it is true, but small countries like qatar tend to gather many services in one unit, so that the country have control over everything,

It's really just an extension of the government. Although little countries in Central America do not do that. The people would not stand for that down here. Freedom is a big deal here where they've actually fought outright with the US to be able to be free.

how do you see the charge, cheap or expensive ?? (sorry i didn't convert the exchange correctly in my previous post, it is 15 $ monthly per extension + one time payment for the installation 164 $)
the voice gateway is in our premise but owned by the telephone company -

the voice gateway is in our premise but owned by the telephone companyWe charge by capacity so it is completely different than with a Centrex system. We don't change by users or extensions since it is a true private PBX.

That price is pretty average from what I have seen similar services in the US.

This is why I recommend this model for most people with more than a few phones. The exact number always depends on the true cost breakdown after phone bill analysis.

What do you mean by capacity?

If you buy any normal server you get "capacity." The amount of "whatever you can do with the CPU, memory and disks" that you have. It's depending on your workload how much you are able to do with it.
Same here. You get a private PBX. You can have thousands of extensions that never talk since they use no capacity. You can have X users on g.711a but fewer on g.726 as it uses more CPU, assuming that you are CPU bound. You can add features as you want, but don't run out of memory or whatever.
Capacity in the most common IT server sense of the word.

So explain how you bill this?

Super easy... it's a flat rate for a capacity level. Only one level is common as we never see customers go over it. Customers who want a live active/active failover system pay for two. Same as every server everywhere bills for capacity. Just opex, not capex. So same model as any cloud IaaS service, just monthly not hourly.

Frankly I was hoping to see some numbers.
Something like...
for 1-10 lines we charge X per line
for 10-50 lines we charge y per line
etc.
DIDs are z more per month, etc. -
That wouldn't be capacity based if there was a breakdown like that. For all intents and purposes it is a set price because the base package handles so much. If you were a large business with 1,000 lines or something I could see that needing to change. But we have big, nationally known brands on the system and some don't even bother to migrate up to larger packages when they are available because they get plenty of capacity as it is (our biggest customer is actually on a system with only 25% of the memory of our current base offering!!)
So while, in theory, there are tiers, it's all purely theoretical. It's just "how many PBXs do you want?

DIDs are z more per month, etc.The whole "Per line" is the wrong term. That is the legacy thinking that is so wrong with people when looking at VoIP costs.
Per the hosted model @scottalanmiller is talking about specifically. It is a charge for the PBX only. Nothing else. Your trunks are your own responsibility to pay for. This is the entire point of a hosted PBX. You pay them for ONLY the PBX. Not everything else. Of course @ntg would be happy to be the team configuring things for you too (so would @Bundy-Associates btw). But you pay for your own usage.
