I assume you are talking about "Hosted VOIP" solutions. There are a few out there. Bandwidth.com is offering this service and even Fonality is in beta stages of hosted VOIP.

It is quite common in the UK but not many providers call it "Centrex". It is more usually called a hosted telephone service, hosted PBX, virtual PBX, virtual switchboard etc.

One advantage of an IP-PBX is that internal calls connect directly whereas using IP Centrex it is likely the speech will go out to the hosting server then back in to the other extension - this is somewhat wasteful of WAN/Internet network bandwidth and could introduce delays/echo in the speech thereby affecting audio quality.

Hello Feptias and thanks for your answer!

Just wanted to know if you can give me a glance on how the uptake of these services are!

I mean, there are a lot of people buying hosted VoIP solutions?

Thanks

I can only say for one of the providers (who I know quite well). Hosted PBX services are a very substantial part of their business, but generally their success in this area is through marketing to specific business sectors and niches; not so much through self-signup of numerous small businesses. They can offer slightly non-standard applications to organisations like police, local gov. etc. Not necessarily "easy" business because every client wants something a bit special - a bit different to the last customer. Much of their business is not even VoIP.

As for the Centrex VoIP market, I can't really say except that there are quite a few companies out there trying to sell it. In my opinion, some kind of customer premises equipment makes a lot of sense if there are more than about 3 extensions because - (a) I don't recommend VoIP as being your only telephony connection - still keep some conventional telephony trunk at least as a backup; (b) daft to make internal calls via the Internet out and back again; (c) support of Hold, Transfer, Pickup features is much simpler with a small PBX on site; (d) the prices for some small PBX solutions are very low.

Challenge: The i-unit group was not satisfied with the audio quality during remote meetings. They were looking for a portable solution with excellent audio quality for use in their conference room but also at their client’s offices.
