Solved difference between IP PBX and IP Centrex
-
Hi guys,,,
i want to know the difference between IP PBX and IP Centrex,
thanks
-
Remove the "IP" from this. The IP just means Internet Protocol and refers to doing these things with VoIP, nothing more. So ignore that.
So the question is PBX vs. Centrex.
A PBX is a private branch exchange, meaning that the customer owns the equipment. It is your own, private phone equipment. Centrex is when there is PBX functionality but it is owned and hosted by the phone provider. Most hosted PBX services are misnomers and are actually Centrex in disguise.

ok, thank you
i see now because i just learned this term and this is what we have actually for one year and half, but i just know the term, lol
before, if someone ask me about our voip installation, i used to say we have a hosted IP PBX
now i know the correct termthank you
-
the ISP provide us with a cisco voip gateway that connect our IP cisco phones to their IP Centrex via copper line (trunk), they charge us monthly per extension (about 20 $/extension ) and give us access to a web management console to manage few things like ring groups or changing extension numbers ...
-
Yes, that would be 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.

Centrex stands for Central Exchange.
PBX stands for Private Branch ExchangeThe correct term today depends really.
Ring Central and 8x8 are Centrex style services.
A hosted PBX is still a PBX and not a Centrex service.
The new term is MultiTenant.
Elastix 3.0 is a a multi tenant system. Thus the rename to Elastix MT. -

VERY different, as I just explained. One is private, one is owned by the service provider.

They are certainly not the same thing. I just defined the difference.

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,
and the IP Centrex is owned by the ISP and shared between multiple costumers, in this case the costumer pay for the service -

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.

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.

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.
