What is voip & business phone systems?

Dig IT Solutions supplies and supports cloud VoIP phone systems for businesses across Hertfordshire, Essex and London, primarily on the 8x8 platform. We port your existing numbers, provision desk phones, softphones and mobile apps, integrate with Microsoft Teams where useful, and prioritise voice traffic on the network we already manage. It replaces ISDN and analogue lines ahead of the January 2027 PSTN switch-off.

Problems we fix

The problems this service exists to solve

  1. 01

    Landlines with a deadline

    Analogue and ISDN lines are being withdrawn, and the lines feeding alarms, lifts and card terminals need a plan too.

  2. 02

    Calls tied to a desk

    Staff at home, at other sites or on the road miss calls or give out mobile numbers, and customers cannot tell who is available.

  3. 03

    Call quality problems

    A VoIP system bought from a telecoms reseller, dropped onto a network nobody surveyed, with no traffic prioritisation.

  4. 04

    Two suppliers blaming each other

    The phone company says it is the network. The IT company says it is the phones. Nobody fixes it.

Scope

What is included

Written into the agreement, not implied. Anything outside this list is scoped and quoted as a project so your monthly cost stays predictable.
  • 01

    System design and number porting

    Call flows, hunt groups, auto-attendants and voicemail designed around how customers call you, with existing numbers ported without gaps.

  • 02

    Handsets, softphones and mobile apps

    Desk phones where they are wanted, softphones and mobile apps for everyone else, so the system follows staff between office, home and site.

  • 03

    Microsoft Teams integration

    Calling from Teams where it suits the business, so one directory and presence status covers chat, meetings and phone calls.

  • 04

    Network readiness

    Quality of service, VLANs and connection checks on the network we manage, so calls are prioritised over file syncs and video.

  • 05

    PSTN switch-off migration

    An audit of every line and what depends on it, including alarms, lifts, door entry and card terminals, with a migration plan before the deadline.

  • 06

    Ongoing support

    Adds, moves and changes handled by the helpdesk, with call reporting and analytics available for managers.

Outcomes

What changes for the business

  • One team responsible for phones and the network they run on
  • Calls answered wherever staff are working
  • Numbers kept, lines withdrawn ahead of the switch-off
  • Per-user monthly pricing instead of line rental and call charges

FAQ

Questions we are asked

Straight answers. If yours is not here, call 020 8482 4020 or 01992 939 365 and ask an engineer.
What happens in the PSTN switch-off?
Openreach is withdrawing the traditional analogue and ISDN telephone network, with the final switch-off scheduled for January 2027. Anything that uses those lines, including phones, alarms, lifts, card terminals and some broadband, has to move to a digital or IP-based service. Ofcom publishes guidance on the migration for consumers and businesses.
Can we keep our existing phone numbers?
Yes. Numbers are ported from your current provider to the VoIP platform. We manage the porting request, timing and any temporary forwarding so callers never hit a dead line. Porting lead times vary by provider, so this is planned early.
Is VoIP reliable enough for business calls?
On a properly configured business network with a reliable connection, VoIP call quality is consistently better than ISDN and far more flexible. Problems usually come from consumer routers, congested Wi-Fi or no quality-of-service configuration. Because we manage the network as well as the phones, those issues are designed out rather than argued over.
How much does a VoIP phone system cost?
Cloud phone systems are priced per user per month, with handsets purchased or rented and calls typically included in bundles. The total is usually lower than ISDN line rental plus call charges, and there is no PBX to maintain. We quote after understanding your users, sites and call flows.
Do you support Microsoft Teams Phone instead of a separate system?
Yes. For businesses already living in Teams, Teams Phone or an integration between the VoIP platform and Teams can be the right answer. We compare the licensing, features and call-handling needs and recommend the option that fits, rather than defaulting to one product.
