Business phone systems for Manchester, Leeds and Liverpool.
Most of the phone system enquiries we take from Manchester businesses start the same way. The ISDN lines are being withdrawn, the old PBX in the comms room is out of support, or staff are working from two sites and a kitchen table and the receptionist cannot find anyone.
We are based at Willan Enterprise Centre in Trafford Park, so a survey in Manchester, Stockport, Salford or Trafford is a short drive, and Liverpool and Leeds are standard call-out rather than a special trip. We have no tribal preference between platforms. We match the system to your team size, call patterns, sites and existing kit, and quote two options where there is a genuine choice.
What we install.
Hosted VoIP, cloud-hosted PBX, Microsoft Teams Voice and hybrid builds, chosen by feature need rather than by label, with the handsets, the number porting and the cutover handled by our own engineers. Offices of 5 to 25 users are covered end to end on our small business phone systems page.
Calls that follow your staff from desk to mobile.
The question we are asked most often is whether one number can ring a desk phone and a mobile without the caller noticing. Yes, and it is the main reason businesses move off separate desk and mobile contracts. On a hosted system every user has one number and one voicemail. A call rings the desk phone, then the mobile app, then drops to voicemail-to-email, in whatever order you set.
Staff can pull a live call from the desk to the mobile and walk out of the building on it. Outbound calls from the app show the office number rather than a personal mobile, which matters when a salesperson leaves. For teams split between the office and home, this one feature usually settles the decision.
Got a project in mind? Let's scope it together.
Weekend installation and cutover.
Phone systems are one of the few network jobs where the whole business notices the moment it goes wrong, so we do the cutover when nobody is calling. For a single office up to 50 users the pattern is a readiness check on the network during the week, handsets configured in our office and delivered ready to plug in, then the port and cutover over one weekend, with the team trained on Monday morning.
Healthcare sites are scheduled around clinical sessions and manufacturing sites around shifts. Thirty days of post-cutover support and active monitoring follow every install, and most clients then take a managed support contract.
A standard install includes
Hosted business phone systems.
Hosted VoIP is the right answer for most businesses of 5 to 100 users. It is cloud-delivered, billed per user per month, works with desk phones or softphone apps, and is the cheapest to deploy and the easiest to support. The tiers have blurred into each other, so we recommend by the features you will use rather than by the name on the tin.
Hosted VoIP
Per-user pricing, desk phones or apps, hunt groups, auto-attendant, voicemail-to-email and one number on desk and mobile. Suits most small and mid-sized businesses.Cloud-hosted PBX
Where you need receptionist queues, IVR, CRM integration, call recording with retention or contact-centre reporting. Gamma Horizon, 8x8, RingCentral, NFON and Wildix.Microsoft Teams Voice
Teams as the phone system, using Direct Routing with your own SIP trunk or Operator Connect through a partnered UK carrier. Increasingly the default for organisations on Microsoft 365 with 50 or more users.Hybrid setups.
Some clients cannot go fully cloud. Call centre operations with regulatory recording, compliance-driven retention, or telephony hardware that is already paid for.
Hybrid is more involved than either pure model, so we only recommend it where it earns its place.
A typical hybrid build
Number porting and SIP trunking.
If you are moving platform you almost certainly want to keep your numbers. Porting is the regulated process for moving them between carriers, usually 5 to 15 working days for a clean port and longer if the donor carrier drags their feet.
We handle the administration, set the cutover date, run a temporary divert during the porting window if needed, and co-ordinate the cut so calls do not fail mid-migration.
Where on-premise hardware is still doing useful work, we supply SIP trunks from Gamma, BT, Spitfire and Voxbone to replace dying ISDN30 lines, then migrate the platform later when it makes sense.

Moving off a bundled desk and mobile service.
A good share of the businesses who call us are on a bundled desk phone and mobile package, BT One Phone being the one we are asked about most, and want to know what replaces it. A hosted system with mobile apps does the same job on an open platform.
One number on desk and mobile, a shared directory, presence, hunt groups and call recording, with the mobile SIM contract separate from the phone system so you can change either without the other. We will map what you use today, feature by feature, before quoting, so nothing you rely on gets lost in the move.
The PSTN switch-off.
BT is retiring the analogue and ISDN network, and any business still on a legacy line or an ISDN-fed PBX will need to move to an IP-based service before it goes. The migration window is closing. If you are not sure what your lines are, we will check at survey and tell you straight.
Our guide to the PSTN switch-off covers what is being withdrawn, who is affected and the order to do things in.
