Business Phones · VoIP & Teams Phone
Phone systems that work the way your team actually works.
Hosted VoIP and Microsoft Teams Phone for UK small businesses. Number porting handled, call recording where you need it, hunt groups that route calls properly. Replaces your aging on-prem PBX or your current provider's eye-watering line rental.
What's included
The pieces that make up Business Phones (VoIP).
Hosted VoIP
If Teams isn't right, we'll deploy a standalone hosted PBX. Yealink and Poly handsets, softphone apps, all the standard features without the on-prem hardware.
Number porting
Move your existing numbers to us. We handle the LOA, the dates, the cutover. If your current provider stalls (they do), we chase Ofcom on your behalf.
Call recording & retention
Compliance recording for legal, financial and regulated firms. Retention configured per regulatory requirement. Encrypted at rest, access logged.
Hunt groups & IVR
Sales calls go to sales. Support calls go to support. Out-of-hours calls go to voicemail or your overflow team. We map your call flow and configure the routing.
Mobile integration
One number for desk and mobile. Calls to your desk ring on your mobile. Outbound calls from mobile show your office number. Caller ID consistent everywhere.

Sits inside our managed service
Business Phones (VoIP) is part of how we run IT — not a stand-alone product.
Telephony is a separate licence on top of managed service. Teams Phone Standard is around £6/user/month plus calling plan. Hosted VoIP starts from £8/user/month including UK landline and mobile minutes.
Common questions
Business Phones (VoIP) — frequently asked.
Should we use Microsoft Teams Phone or a separate VoIP system?
If you already have Microsoft 365 Business Standard or above and most calls are internal or scheduled, Teams Phone is usually the right call (pun intended). It's one less app, one less licence stack, one less vendor. If you have a contact-centre style team taking high-volume external calls, a dedicated PBX often handles queueing and reporting better. We'll recommend based on your call patterns, not on what we earn the most margin on.
Can we keep our existing phone numbers?
Yes — number porting is included. Allow 10 working days from receipt of the signed LOA (Letter of Authority). Some legacy providers drag this out; we know the tactics and chase Ofcom if they breach the porting code of practice.
Will my existing handsets work?
If they're SIP-compatible (most Yealink, Poly, Cisco and Snom handsets from the last 5 years are), yes. We'll factory reset and re-provision them onto our platform. If they're proprietary to your old provider, they're paperweights.
What about ISDN — that's getting switched off, isn't it?
Yes — BT's PSTN switch-off is happening now, with full retirement by January 2027. If you're still on ISDN30 or analogue lines, you must migrate to VoIP before then. We're moving clients across in batches; the longer you wait, the busier the porting queues get.
Do you provide call recording for compliance?
Yes. Configurable per user, per group or always-on. Retention set to your regulatory requirement (typically 6 months for general business, 5–7 years for financial services). Recordings encrypted at rest, access logged for audit.
What happens if our internet goes down?
Calls fail over to mobile via the Teams or VoIP app on each user's phone — assuming they have 4G/5G signal. For sites where that's not reliable, we deploy a 4G failover router on the office circuit. Inbound calls can also auto-divert to a list of mobiles or another office at the carrier level.
Can we have a contact-centre setup with queues and reporting?
Yes. Teams Phone has Queues App and we can layer in solutions like Anywhere365 or Landis Contact Center for fuller capability. If you need wallboards, supervisor barge-in and historical reporting on agent performance, that's where we'd go.
How much does it cost compared to our BT contract?
Almost always less. Most clients save 20–40% on monthly cost in year one once line rental, system maintenance and call charges are consolidated. We model it against your last three months of phone bills before you commit, so you can see exactly where the saving comes from.
