How private voice communication works

1. A user places a call from your app

A user on your service calls a local virtual number to hail a ride, book a place to stay or to purchase an item from a seller in your marketplace.

2. The other party picks up

Vonage APIs connect the caller with the other party in your marketplace. Neither party sees the other party’s personal phone number; they see only the virtual number your application provisioned for the service.

3. The conversation takes place

With their personal phone numbers masked, the parties talk and possibly come to an agreement — for a ride, for goods to be purchased through your marketplace or whatever it may be.

4. Analyse trends and discover insights

Though the parties can’t see each others’ number, you can. You can generate reports from the console to understand who spoke with whom and when, analyse trends and discover insights that are important to your business. If the call was recorded, it can be transcribed and analysed for further insights.

Why choose Vonage APIs for private voice communications?

The highest-quality voice

Vonage APIs connect directly to the Vonage MPLS network and to Tier 1 carriers that provide the highest quality voice services. In addition, with data centres in all regions of the world and our automatic location-based routing, our platform delivers the lowest latency and the high reliability your business-critical applications require.

Real time provisioning

With support for real-time number provisioning, you pay only for the numbers you actually need. No need to over-provision and park numbers just in case you need them.

Per-second billing

With per-second billing (most countries), you don’t need to pay for unused partial minutes, adding to the savings.

Split call recording

Vonage APIs will soon support the recording of each call leg separately so you can improve transcription accuracy significantly. Recording is in stereo, with one channel recording what the user hears and the other what the user speaks. This separation improves the quality of transcriptions significantly so you can improve analysis and gain new insights.

All the insights you need

The Vonage APIs dashboard includes all the data you need to manage your business including call volume, cost and detailed call records. You can also incorporate the data into your own analytics using our management API.

Real time event data

The Vonage Voice API delivers real-time event data to your application so you can track it or even change the call flow on the fly. Real-time events include changes in call state (ringing, busy, etc.), answering machine detection, the price of the call and more.

"With [Vonage APIs], we don't need to worry about establishing and maintaining relationships with individual carriers and we don’t have to teach our developers to communicate in non-standard ways. We couldn’t be more satisfied with both the quality and ease of use of [Vonage APIs]. —Glenn Lee, Senior Product Manager for CentraCX
