How it works


Business Discovery

We start all our business relationships by really getting to know your business, your challenges and the opportunities to streamline and improve your outsourced switchboard experience.


Bespoke Call Handling

Our Customer Success team streamlines the processes and corporate call-handling scenarios to outline a consistent, high quality client experience tailored to your individual organisation considerations.


Data & Insights

Our advanced technology is tailored to deliver your call handling requirements and generate specific data insights and reporting to support ongoing excellence.


Go Live

Your selected Virtual Personal Assistants are trained on your organisation, culture and processes, before going live and managing your business phone answering experience seamlessly and professionally.


Improve your client experience

Our technology allows us to identify callers, including your VIPs and anticipate their needs for an excellent call experience. 99.9% of business calls are answered.

Continuous Improvement

Unique data insights and management information allow you to make informed decisions, increasing productivity and supporting continuous improvement.

Increased Efficiencies

Swift identification of calls ensures that cold calls are rapidly terminated, and new business calls are successfully escalated so that no opportunities are lost.

Cost Reduction

We reduce your costs by removing the need for recruitment and in-house training, whilst still providing consistent client experience without the risk of business disruption due to absence or staff turnovers.


"Up to 40% of full-service law firm calls are new business calls." Can you afford to risk losing any?

One of the world’s leading financial service providers commissioned us to implement a Cold Call Filter on their outsourced switchboard service. In an average month we filter over 650 calls, saving their reception team nearly 7 hours of call time, and ensuring they never miss a new business opportunity.
