We are now an Approved Partner of Faster Britain.

CritchCorp Computers Ltd is an approved partner with Faster Britain.


Open Reach has given notice that it intends to switch off all PSTN and ISDN lines by December 2025. Our VoIP solution is ready to go and we can transfer your PSTN or ISDN phone number across so you don't lose it. OpenReach's Stop-Sell strategy for all PSTN & ISDN lines from 5th September 2023. This means you will not be able to get new services, nor transfer existing services.

In line with the above statement, we have only listed below the current technologies


SIP Trunks

We can provide a SIP trunk to be used with your PBX or supported device. You get 2 lines as standard and can then add extra lines as required. We can also port your numbers across. You can then manage your numbers from the control panel; routing, external Voicemail etc.

Hosted PBX Account

We take care of the server side. You have control over how you set your account up, with powerful tools, such as:

  • Call routing – Control how each of your numbers will be handled via a powerful GUI.
  • Set opening hours to be used in the call flow.
  • Number divert – Divert each numb in your account, if needed.
  • Caller menus (IVR)
  • Voicemail controls
  • Music on hold
  • Audio library controls
  • View all the feature codes
  • User control
  • Group controls
  • Group controls
  • Device controls
  • Shared Address books
  • Call statistics and logs

Your account can have as many numbers as you like, and each user on the account gets 1 line associated with the account. So, if you have 3 users, you will have three lines on the account. The lines are shared between everyone, so this means that you can make/receive 3 simultaneous calls. Add more users, get more lines.

VoIP phones

We can supply a range of VoIP phones that are compatible with our system, otherwise you can check the list of compatible devices as updated from time to time, here.

Broadband Internet

We use multiple wholesale broadband providers to ensure we can give the best service to our clients. We buy wholesale much like most broadband providers do, but we give you the best connection and that is usually the business version rather than the home version. Other companies give you the cheapest version, but we understand how the internet works and how supply works. The home versions may say that they are the same speed, but in actual fact they have greater, in some cases much greater, connection ratios. You want to go faster, stop sharing the line with so many others in your area. Home lines are generally shared with 300 other Home subscribers whereas business lines are a maximum 50 other business subscribers. The business product is quicker because fewer people are sharing the line, although both amy have the same bandwidth.

If the internet is important to you or your company (some have a critical business needs for internet connections) then you really should look at the new entry level Leased Lines and even the full Leased Lines. They all come with SLAs and a phone number to call 24 hours a day if there is a problem.

SOGEA (Single Order Generic Ethernet Access)

FTTC has been the norm for the last few years; FTTC stands for Fibre To The Cabinet. SoGEA is the same as FTTC, but without the need for a telephone line rental as well. Open Reach has run Fibre from the exchange to most of the green boxes and this has enabled your internet connection to run along fibre cables to the green box and then normal copper telephone lines from the green box to your house/office. A vast improvement on the old ADSL 2+

FTTP (Fibre to the Premises)

The new standard, where it is available. The roll-out of Full Fibre continues, and you may well have seen the Open Reach or other contractors, such as City Fibre, digging the roads up. They are trying to lay fibre everywhere, and they are making a good headway in to it. There are several options for Full fibre, all the way up to 1000Mb download speeds, although this is not always a good option as it is reported that the BT router, and many other routers from other providers cannot actually handle 1 GB connection in full and so you lose a lot of your bandwidth just because of their free router. We have several options when it comes to routers, but they will be able to handle the whole internet bandwidth that you are provided with. We mostly provide businesses with internet, but we are happy to provide residential properties as well and have a few of these on our books; we are currently looking in to offering other services such as TV to go with th e residential product. Not only that, but we only provide reliable connections and high quality routers. You can of course provide your own router if you wish, but remember; if it is cheap, then it is cheap for a reason.

For all your Broadband needs, get in touch with your full address and phone number, and we will let you know what is available in a no obligation quote.

Leased Line Internet

Leased lines are the best broadband you can get. They utilise similar technology as home broadband, but with several advantages. The best leased lines are full fibre all the way, they can offer up to 10 GB speeds in both directions, these as you can imagine are rather more expensive than any basic internet connection. The prices have however fallen and with new technologies available you can now get an EoFTTC connection for around £150/month and with FREE installation (subject to survey). This is an Ethernet connection over Fibre To The Cabinet, so it is quicker to start with, then you add in the leased line common elements, and you can’t beat it for home based or small businesses. The SLAs mean you will be back up and running as quick as possible, if there is ever a problem, otherwise they start to pay you! You also get a dedicated 24-hour phone number to call if there is a problem with the line itself.

Common elements for leased lines are:

  • You don’t share the line with anyone else, it is all yours. Normal residential broadband is shared between 300 other subscribers and business broadband is usually share with up to 30 other subscribers (which is why getting a business connection in your home usually works better and faster than a home product).
  • You get an SLA on a leased line. This is a contractual agreement to get the service back up and running with in a set time, or they face compensating you. This is different again from normal connection because they only come with an aim to fix and absolutely no guarantees. You can pay for enhanced care levels, but they are still an aim to fix not an SLA until the top levels, and then you are usually above the cost of a leased line.
  • They do not require you to pay for a phone line separately.
  • They come with an out of hour’s phone number to call if there is a problem that needs urgent attention and an engineer can come out 24/7, if they can get access to the site.

Therefore, if your business requires broadband, and yes, we have seen businesses fail because their BT retail connection could not be fixed for 8 weeks and much, much longer for a sky connection, then you really need to get a leased line. It is amazing how much your business depends on your internet connection these days, and it is generally not until it’s gone that you realise this. Try it today, disconnect your internet connection and see how long you can last without it! Most won’t even do this, if that’s you, then you need a Lease Line, and as the EoFTTC products are far cheaper it makes sense to get one now.

Don’t get caught short. Contact us to get a free quote for a leased line, with no obligation. Once we receive enough details to give you an accurate quote, you can decide to progress or not. Once ordered and signed for, you are committed to the term.
