IVR & Media Services

Build modern IVR and Unified Communication solutions with our API

Build IVR, UC and next gen telecom solutions the modern way, no hardware or software deployments – just integrate to our feature-rich and easy-to-use mediaservice API.

Use our modular functions to build scalable solutions for your enterprise, contact-, call- or support center customers.

Out-of-the-box capabilities

Key capabilities that are just an API away.

Full suite of modern and modular telecommunications functions provided in our feature-rich and easy-to-use Mediaservice API.

Playback audio prompts from files or URLs. Used as part of an IVR call flow or in other modern telecom solutions.

Start and stop call recording for calls handled by the mediaservice API as well as functions to record phrases within an IVR call flow.

Detect and act on DTMF signaling within an IVR flow. The DTMF information is sent to your application with an API callback letting your application decide the next step.

Integrate natively with Amazon Polly’s and Google’s text to speech APIs providing a wide range of languages and voices for text to speech generated prompts.

Accept, reject, drop, queue or transfer any call to any other service or destination such as your SIP devices, WebRTC clients and SIP trunks. A key building block when building IVR call flows.

Callbacks notify when participants are leaving a mediaservice session connection, and the response provides an action about what to do with the remaining participant.

Use case examples from the Mediaservice API​

  1. Playback audio prompts from files or
    URLs based on DTMF detection
  2. Build advanced Interactive Voice
    Response (IVR) call flows
  3. Record voice calls
  4. Build cloud-hosted PBX
  5. Direct incoming calls to your Unified Communications platform e.g. auto attendant
  6. Build call queues

Build the application you need!​

Applying contact center services have never been easier! Gone are the days of tedious implementation projects or complex hardware or software deployments. Now, all you need to do is to let us know how you want your incoming calls to be treated and where they should be routed, and we will carry out all signaling and media processing necessary.

From easy “answer and playback a voice prompt” to sophisticated and complex interactive call scenarios that imply voice or media processing – that’s up to you! You decide the media interaction best suited for your application case – we run the underlying communications platform for you.

Remove the HW and SW hassle!​

Traditionally dedicated media and application server hardware and software have been required to enable multimedia services. This involve installation, implementation, operation and maintenance – all of which require specific competence, space and thus tend to be costly and time consuming.

With our managed service from the cloud you can avoid the cost and hassle with a HW and SW based infrastructure. Build your modern services with our API and reduce time to market dramatically!


Avoid the HW & SW hassle – build your modern telco solutions with our feature rich and easy-to-use API!

Cloud Native

Avoid the hardware dependency, vendor lock-ins, and the never-ending software upgrades typical in traditional purpose-built or COTS-based media or application server deployments.

Scalability & Reliability

With our serverless backend, instant scalability is secured right from the start. The robust and reliable design enable the development of mission-critical interactive media applications.

Simplified Operations

With our managed services model we will run the communications platform for your media interaction applications. We take care of the complexity of the underlying SIP and WebRTC signaling and media flow.

Flexible Customization

Define the call control and media playback functions of your choice. Advanced IVR call flow, basic call termination, cloud-hosted PBX or call center functionality? It’s up to you! Invoke any functionality with the REST API.

Pay only for what you use

With our serverless backend and microservice based architecture you only pay for the traffic used. In our customer portal you get instant overview of your service usage providing a deterministic cost overview.

Wide range of audio codecs supported​

PCMA, PCMU, G.722, GSM and OPUS.
