What does AMVIA's business VoIP cover for Sheffield firms?

AMVIA gives Sheffield businesses a fully managed cloud phone system: number porting, handset and softphone setup, call routing, and ongoing support from UK-based engineers. We design the deployment, configure it to how your team actually works, and stay on for the lifetime of the system.

What you get:

• Cloud phone system — desk phones, mobile and desktop softphones on one platform
• Number porting — keep your existing Sheffield numbers across the S and DN postcodes
• Microsoft Teams calling — make and take external calls inside Teams
• Managed connectivity — we can supply the broadband or leased line underneath
• UK-based support — qualified engineers, clear SLAs, defined response targets
• Security built in — call encryption and fraud controls as standard

On-site attendance across the S1–S14 area is arranged for hardware installs and troubleshooting; day-to-day management is handled remotely.

Why are Sheffield businesses moving to VoIP now?

Two things are driving the switch: the old phone network is being retired, and VoIP simply does more. The UK's analogue PSTN and ISDN network is being switched off, with the industry deadline now 31 January 2027 — every business still on traditional lines has to move before then.

Adoption is already well advanced: an estimated 31% of UK businesses had switched to VoIP by 2025, and over two-thirds of UK landlines have already been upgraded to VoIP (UK industry data, 2025). Ofcom's migration to digital landlines is the reason the legacy network is going away (ofcom.org.uk).

Moving early means a planned migration instead of a forced one. We handle the PSTN switch-off for Sheffield businesses from porting through to system configuration.

How much does business VoIP cost in Sheffield?

Pricing is fixed monthly per user — the same plans AMVIA runs UK-wide, with no hidden charges. Sheffield businesses pay the standard rate, and the connectivity to support it is quoted separately based on your site.

If you need a dedicated line to guarantee call quality, a 100 Mbps leased line in urban areas starts from £69/month. We will tell you plainly whether your existing broadband is enough before you spend on connectivity you do not need.

Can you provide Microsoft Teams Direct Routing in Sheffield?

Yes. AMVIA deploys and manages Microsoft Teams Direct Routing for Sheffield businesses, so your Microsoft 365 environment can make and receive external calls through Teams. It is the most popular option for firms that want calls, chat and meetings on one platform instead of a separate phone system.

Teams Phone with Direct Routing connects your tenant to the public telephone network through a managed session border controller — Microsoft documents the architecture in detail (learn.microsoft.com). We handle the setup, licensing and number management so your team just makes calls.

What internet connection do I need for VoIP in Sheffield?

Each simultaneous VoIP call needs roughly 100 Kbps of bandwidth, so the real question is how many calls run at once. For Sheffield businesses with 10 or more users, a high-quality FTTP connection or a dedicated leased line is the safe choice for consistent call quality.

Because we supply both the VoIP system and the connectivity, we size them together — no finger-pointing between a phone provider and a separate ISP when a call drops.
