When I signed up for Acefone, I had very little VoIP knowledge, but the technical support was second to none, even for companies with limited technical skills. Added bonus: it works out cheaper than my existing single BT phone line.

Lee M.

Our company has been using Acefone from the beginning and we have never had any issue with the service. Their support is amazing, always happy to help and always polite. If you are looking for VoIP, you cannot find a better provider.

My experience has been very positive. The software is easy to use and integrates well with our existing system. The phone was configured in minutes by a remote technician. I've never had to ask for assistance over the last 12 months.

Gordon R.

Director, Airlines/Aviation

Acefone is easy to set up, thanks to great help from customer service. The software has many useful features. I chose Acefone because a real person talked to me and helped me pick what I needed. They resolved all my queries there and then.

William A.

Director, Financial Services

Acefone's onboarding process is great — the company helped me in every way imaginable. The support representative was really informative and patient with all my queries. The software appears to cover all bases as well.

Wish to learn more about Acefone’s Voice APIs (FAQs)?

What is an API?

An API also known as Application Programming Interface, acts as a middleman between different software programs, allowing them to communicate and exchange data with each other. It's a set of rules and specifications that define how these programs can interact and share data with each other. By providing a medium between applications, they enable seamless data exchange, faster development, and innovative features, ultimately making your business operations smoother and richer.

What are the types of APIs Acefone offers?

Acefone offers several types of APIs to tailor your business phone system according to your unique operational requirements. Explore these APIs at Acefone’s API Docs.

How do APIs work?

Voice APIs act as a bridge between VoIP systems, which handle the actual voice calls over the internet, and other applications. These APIs translate spoken language into instructions the VoIP system can understand and vice versa. This translation allows applications to leverage VoIP features like initiating calls, sending voice messages, or transcribing conversations.

How many API types are there?

Despite the different classification that determine the number of API types, they can be narrowed down to three.

By Access

Public APIs, Private APIs, Partner APIs
By Purpose

Web APIs, Database APIs, Payment APIs, Voice API, SMS API
By Design

REST APIs, SOAP APIs, GraphQL APIs

Can Voice APIs make calls in bulk?

Yes, bulk calling features are available with our voice API.

What is the role of WebRTC?

WebRTC allows you to integrate voice with Web applications to enable all call-related actions like dialing numbers, answering calls, and more.

How do APIs help maintain data confidentiality?

Acefone offers number masking solutions that hide contact details of both the parties involved. You’re guaranteed confidential communications and data privacy with secure connections.

Do Acefone’s telephony solutions allow voice recording and call capturing?

Definitely. Our call recording features help you keep track of all data and quickly review it at any time. Moreover, the files are stored on a secure cloud server so only authorized personnel can access them.

How to add IVR script through API?

Some APIs allow you to manage individual components of an IVR script, such as uploading audio recordings for prompts and more. With Acefone, you can select a code from our range of templates in text to speech API to create custom scripts for the IVR.
