Starting in the VoIP world
-
Yup. Not much different than the old world, just on converged (IP) networking. Connections to the public phone system, your PBX and phones to talk on.

Think something confusing me a bit is the SIP Trunks/Incoming Numbers/Channels.
Lets say I want the store to have a single number but out of the 5 extensions inside 3 can be "on" a call at one time.
Do I need 3 SIP Trunks GEO numbers and merge them to a single number or can I buy SIP trunks with a single incoming number and have multi "channels"??*Been a very long time since I even looked at VoIP stuff

Trunks are really a way for telcos to conform you to the old way of buying phone service. Just buy DID's and pay for the minutes. I think simwood at least is a good provider where you are.
With metered service you can have as many active calls as you want, and you only pay for what you use.

You need one SIP trunk and in your PBX config, you tell it 3 max calls allowed.

You still need a trunk. But SIP trunks are not tied to a DID or a fixed amount of concurrent calls, unlike POTS and PRI.
POTS trunk = 1 DID and 1 concurrent call (yeah, yeah, old school 3 way calling gimmick makes 2)
PRI trunk = 0+ DID and 23 concurrent calls.
SIP trunk = 0+ DID and 1+ concurrent calls (sane soft limits generally imposed by providers for toll fraud).Some VoIP providers sell SIP with limits like POTS because people are stupid and have no idea what they are buying.

What do I need to know and watch out for when starting to look at the VoIP world instead of normal PSTN/ISDN PBX systems.
We are setting up a new store in May and will need a phone system. Normally the PBX would be a BCM 50 or similar, two lines/channels then 3-4 internal extensions.
So what would I need if it was either Hosted VoIP PBX or on prem PBX??
Guessing a box (bought or rented) some phones and SIP Trunks?Trying to see what the costs are as ISDN is set to rise more and more as BT want people off them lol.,
In your case, with lots of small locations, the simplest ting to do is simply created a PBX on some infrastructure (owned or rented) and then turn up the new shop. As time and funds permit, you can continue adding existing locations.
The added benefit is that as old sites come online, your calling charges will go down, not only because of the generally lower cost of SIP versus ISDN/BRI but because you can start leveraging extension dialing. So inter-store calling is no longer even hitting the PSTN.

Looking forward to reading and learning on this thread, as eventually the "replace our aging AltiGen PBX and T1" project will come to the front burner.

So if I just bought a trunk form someone like this:-
http://www.voipon.co.uk/uk-voip-geographic-numbers-p-268.html
That's £35 for the year I could have several calls on this at once? Or do I need to find a SIP provider that will give me a trunk with lots of capacity to speak? -

I would but management would prefer to see a "Managed" service

I promise to come in less than @Minion-Queen just because I need to convince the boss to fund a trip over. -

Generally you should have single low cost for the DID and simply pay per minute for usage.

@hobbit666 could be worse. You could have one of those physical DID handsets. You get those 50% of the time I hear.

An example of this... nearly all PRI today are delivered via a single SIP trunk. It's SIP from end to end with an adapter put on at the client site to convert the single SIP trunk into a PRI with 23 digital lines in it. A single SIP trunk can deliver a theoretically unlimited number of "lines" or concurrencies. So you could, for example, have 100 PRIs delivered over one SIP trunk.

There is Twilio and a Telnyx in the U.K. As well,
