VoIP for Marketing and Creative Agencies in the UK

Agency life is busy. Account managers are on calls between client visits. New business is chasing briefs and pitching. The studio is mid-production. Finance is chasing an invoice. And the phone is ringing.

A phone system built for a single-location, desk-bound team does not work for a modern agency. VoIP does.

This guide covers what to look for in a VoIP phone system if you run a UK marketing or creative agency — and why the details matter more than you might think.

The Agency Communication Reality

Most agencies have at least four distinct groups of people who use the phone differently.

Account managers are on calls throughout the day. When they are not at their desks, they are on client visits, at shoots, or at events. They need to be reachable on an agency number — not a personal mobile.

The new business team makes outbound calls and takes inbound enquiries. Those calls need to be tracked. The details of what was discussed need to be captured.

The studio and production teams get dragged into client calls at short notice. When an account manager is tied up, someone needs to pick up.

Admin and junior staff handle internal calls, supplier queries, and overflow. They need a professional number but do not necessarily need the full feature set.

A good VoIP system handles all four groups from a single platform. You do not need four systems, four contracts, or four invoices.

Auto-Attendant: Route Calls to the Right Team

When a client rings the main agency number, they should not have to explain themselves to whoever picks up first. An auto-attendant solves this.

Press 1 for new business. Press 2 for client services. Press 3 for accounts. Press 4 for the studio.

That is it. Each department gets its own menu option. Calls go where they need to go without anyone acting as a human switchboard. For a client ringing with a project query, it saves time. For a prospect calling for the first time, it gives the right first impression without requiring a receptionist.

The auto-attendant is available on the Samurai plan at £14.99 per user per month — and that is the plan most client-facing people in an agency will sit on.

Call Recording: Protect the Agency When the Brief Changes

This one is underused by agencies and it should not be.

A client gives a verbal brief on a call. Everyone is clear. Six weeks later, the client comes back and says the direction was wrong. They claim the brief was different to what you understood.

If the call was recorded, the conversation is there. You play it back. The brief is confirmed or corrected. The dispute ends.

Call recording is not about distrust. It is about accuracy. It protects both parties. Clients who know calls are recorded give better briefs. Account managers who know calls are recorded make better notes.

Recording new business calls is equally valuable. When you are pitching, the client gives you information about their business, their challenges, and what they are trying to achieve. If a second person cannot always sit in on those calls, recording them means nothing gets missed.

All recordings are stored and accessible without needing separate software. It is part of the Samurai and Shogun plans.

Mobile App: Stay on the Agency Number When You Leave the Office

Account managers who give clients their personal mobile number create a problem for the agency. The client relationship then belongs to that person, not the agency. When that person leaves, the client goes with them.

The VoIPninjas mobile app fixes this. Account managers use the agency number on their phone. Calls in and out go through the same VoIP system. Clients see the agency number. Voicemails go to the agency. The number stays with the business.

That matters when an account manager leaves. The DDI stays with the agency. The client does not have a personal number to ring. The relationship transitions cleanly.

The mobile app is included on all three plans — Ronin, Samurai, and Shogun.

DDI per Account Manager: Direct Lines That Stay With the Agency

A DDI (Direct Dial-In) number gives each account manager their own direct line. Clients can call their account manager without going through a switchboard. It feels personal and professional at the same time.

The critical thing is ownership. The DDI belongs to the agency, not the account manager. When someone leaves, the number is reassigned to their replacement. The client rings the same number and speaks to the new contact. There is no interruption to the relationship and no risk of a departing employee taking calls from agency clients on a personal number.

Every plan includes a DDI.

Ring Groups: When the Account Manager Is Not Available

An account manager is in a meeting. A client rings their DDI. With a ring group set up, the call overflows to the wider account team — not to voicemail.

Ring groups are particularly useful for agencies where account managers work across multiple clients and are frequently out of the office or on other calls. The client gets through. Someone picks up. No one is left waiting.

Ring groups are available on the Samurai and Shogun plans.

Voicemail-to-Email: Never Miss a New Business Enquiry

New business enquiries do not always come in during office hours. A prospect looks at your website at 8pm, finds your number, and calls. They leave a voicemail. By morning, that message is already in your inbox.

Voicemail-to-email converts each voicemail into an audio file and sends it to a nominated email address. No one needs to remember to check a voicemail box. The message arrives in email, where it can be forwarded, followed up on, or filed.

For agencies, this is especially useful on the new business and main reception lines. It is available on the Samurai and Shogun plans.

Shogun for Agencies With International Clients

If you work with clients or suppliers in Europe, the US, or elsewhere, domestic-only call allowances become expensive quickly.

The Shogun plan at £24.99 per user per month includes unlimited UK calls and calls to 55 countries. For account managers who are regularly on calls with international clients, it removes the bill uncertainty. One flat monthly cost.

Not every person in the agency needs Shogun. You can mix plans. Put client-facing account managers with international clients on Shogun. Put everyone else on Samurai or Ronin.

28-Day Rolling Terms: Built for How Agencies Actually Operate

Agencies grow in bursts. You win a large retained account and need to bring on three more account managers. You hire a team of freelancers for a six-month campaign. You are pitching for a contract that would double your headcount.

A 12 or 24-month contract does not work for that kind of growth. You end up paying for seats you do not need or scrambling to add users mid-contract.

VoIPninjas runs on 28-day rolling terms. No contracts. You scale up when you need to and scale back when the project ends. If you are onboarding a freelancer for a campaign, you add a user. When they leave, you remove it. You are never paying for seats that are not in use.

Which Plan for Which Role

Ronin at £5.99/user/month works for junior staff, admin, and anyone who needs a professional number and a mobile app but does not need call recording or an auto-attendant.

Samurai at £14.99/user/month is the right fit for most client-facing account managers. You get call recording, auto-attendant, ring groups, DDI, voicemail-to-email, and 750 UK minutes per month.

Shogun at £24.99/user/month is for account managers with regular international calls or anyone who is on the phone constantly and needs unlimited UK minutes without counting.

You can mix plans across your team. You are not locked into putting everyone on the same tier.

Frequently Asked Questions

Can we mix plans across our team — for example, Samurai for account managers and Ronin for admin staff?

Yes. You assign each user their own plan. There is no requirement for everyone to be on the same tier. Most agencies put client-facing staff on Samurai or Shogun and use Ronin for junior or administrative roles.

What happens to a DDI if an account manager leaves?

The DDI belongs to the agency, not the individual. When someone leaves, you reassign their DDI to their replacement. Clients ring the same number and reach the new contact. The number does not leave with the employee.

How does call recording work and where are the recordings stored?

Calls are recorded automatically on lines where recording is enabled. Recordings are stored within the VoIPninjas platform and can be accessed and downloaded by administrators. You do not need separate software or storage.

We take on freelancers for campaigns. Can we add and remove users without a penalty?

Yes. Plans run on 28-day rolling terms with no contract. You add a user when a freelancer starts and remove the seat when the engagement ends. You only pay for what you are using.
