Telephone interpreting tailored around your needs

Whether you are responding to urgent enquiries or building a structured approach to language access, this service provides real-time support backed by experienced linguists and our dedicated team.

Access to a wide range of languages

You can connect with professional interpreters across a broad selection of language pairs, including commonly requested and less widely spoken languages.

From Arabic, Spanish and French to Hindi, Somali and Portuguese, our network is designed to support diverse communication requirements. We can also help you explore the full range of available languages through our brochure, giving you visibility of the options available for your organisation.

Please note that telephone interpreting is not suitable for signed languages, such as BSL interpreting.

24/7 access for urgent and ongoing requirements

Once your service is set up, you have access to interpreters around the clock. In many cases, you can connect to an available linguist within minutes, making this approach well suited to urgent requests and fast-moving environments.

At the same time, it can be scaled to support high-volume usage through SLAs or frameworks, while still remaining flexible enough for one-off assignments when needed.

Our role does not end with a single booking as we can support ongoing requirements or a wider mix of interpreting solutions.

Dedicated support, delivered securely

Every client is supported by a dedicated account and project management team who understand your requirements and help ensure consistency across your interpreting provision.

Our services operate within GDPR-compliant and ISO 27001-certified systems, supporting secure handling of your data and conversations.

Many of our linguists are also members of recognised professional bodies, such as ITI, NRPSI and CIOL.

How our over-the-phone interpreting service works:

We provide a straightforward and reliable approach to over-the-phone interpreting, allowing you to access professional language support as and when you need it.

1. Understanding your requirements

We begin by discussing how you plan to use the service, whether that is for one-off calls or as part of a wider interpreting provision. This allows us to set up your access appropriately, including any service-level agreements, frameworks or usage expectations.

Your dedicated account manager will guide you through the available options and ensure the service aligns with your operational needs.

2. Simple access and connection

Once your service is set up, you can access interpreters 24/7.

When a need arises, you simply request the required language and connect to an available linguist, often within minutes. This makes telephone interpreting particularly effective for urgent situations.

3. Ongoing delivery and support

Each interaction is delivered in real time by professional linguists, with your account and project management team available to support ongoing use.

We can help you scale usage, maintain consistency through structured agreements, and adapt the service as your requirements evolve over time.

Additional: VoIP integrations

Our over-the-phone interpreting service can work seamlessly alongside modern VoIP and call handling systems, making it easy to embed language support into your existing workflows.

If you have specific technical or operational requirements, our team can work with you to ensure the service is aligned to your setup and usage model.
