Area Overview

Business Telecoms in Stratford, E15

Stratford has changed more than almost any part of London since the 2012 Games. The former Olympic site is now Queen Elizabeth Olympic Park, surrounded by new office districts, university campuses, cultural venues and thousands of homes, while the older town centre around The Broadway and Romford Road still supports a dense mix of independent businesses.

The International Quarter London beside Stratford International station has brought large-scale office space to E15, and Here East on the edge of the park houses technology, education and creative organisations in the former broadcast centre. East Bank adds university and cultural campuses to the mix.

With some of the best transport links in London, Stratford is a natural base for teams who split their time between the office, home and client sites. That makes cloud phone systems and Teams calling the default choice for many new occupiers, while established firms in West Ham and Maryland are often replacing older lines and PBX systems.

The Business Landscape in Stratford E15

Stratford's business base now runs from large financial and public-sector offices to small creative studios. Professional services, technology and digital businesses have grown quickly around the Olympic Park, while retail and hospitality remain major employers in and around the town centre.

Construction has also been a constant in E15 for over a decade, with contractors and their supply chains needing phones that work on site, in temporary offices and on the move. Mobile apps, hunt groups and calls that follow staff between locations are standard parts of our Stratford setups.

Telecoms Guidance

Business Phone Systems & VoIP in Stratford, E15

A plain-English guide to business VoIP for Stratford firms, covering the questions that come up most often on our calls.

Phone Systems for Stratford's Hybrid Offices

Many Stratford businesses work in flexible office space and don't want hardware tied to a single floor. A hosted platform such as Gamma Horizon, or calling built into Microsoft Teams, lets staff take calls on a laptop, mobile or desk phone and keep the same 020 number wherever they are.

If you move within the area, or between serviced offices, your phone system simply moves with you. There's nothing to re-cable and no lines to transfer.

Broadband and Leased Lines for VoIP in Stratford

Good call quality depends on the connection underneath it. We check broadband availability for your Stratford premises and can supply business-grade fibre or a dedicated leased line.

For larger sites, a leased line with a backup connection keeps calls running even if one circuit fails.

VoIP vs Traditional Phone Lines in Stratford

A traditional line carries one call at a time over copper and offers little beyond basic forwarding. A VoIP phone system carries voice over your broadband or a leased line, so you can run as many simultaneous calls as you have licences, add users in minutes and take calls anywhere.

For most Stratford businesses, VoIP also lowers line rental and call costs, and brings features such as auto-attendants, call recording and voicemail-to-email as standard.

Common Questions

Frequently Asked Questions — Stratford VoIP

Can Stratford businesses use Microsoft Teams as their phone system?
Yes. We can add external calling to Microsoft Teams through Direct Routing or Voiceflex Flow, so your team makes and takes 020 calls in Teams. Many Stratford offices combine this with a few desk phones for reception or meeting rooms.
Can I keep my 020 number if my Stratford business moves to VoIP?
Yes. Any 020 number can be ported to a VoIP phone system with no gap in service. T2K Voice & Data manages the porting for you, whichever platform you choose.
What does VoIP cost for a E15 business?
Hosted platforms such as Gamma Horizon or 3CX typically cost around £10–£20 per user per month for a Stratford business with 5–50 users. Larger offices and contact centres usually suit Mitel or 3CX on custom pricing, and every quote is itemised.
We're in serviced office space in E15. Do we need our own lines?
No. A hosted VoIP system only needs an internet connection, which most serviced offices provide. Your numbers stay with you if you move buildings, and you can add or remove users as the team changes.
Will an engineer need to come to our E15 site?
Usually there's no need. We configure Stratford systems remotely and fix most faults the same way, which is quicker. Jobs such as new cabling, an on-premise PBX or a large multi-floor rollout are the exception, and we agree those visits before you sign.
Do Stratford businesses need to replace analogue and ISDN lines?
Yes. Openreach is retiring the UK's traditional PSTN and ISDN network, exchange by exchange, so businesses still on analogue lines, ISDN2 or ISDN30 need to move to VoIP, SIP trunks or a digital line replacement. Check where your lines stand with our PSTN switch-off checker.
