Try It FreeContact Sales

BENEFITS

Facilitate communication while protecting privacy

Protect user privacy
  • Protect users’ privacy by connecting them without exposing their real phone numbers.
Avoid revenue leakage
  • Keep conversations between users on your marketplace to avoid off-platform transactions.
Gain new insights
  • Track, record, and analyze calls to gain new insights on your business.
How it works
Connect your marketplace users without exposing their phone numbers
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.
The other party picks up
Nexmo’s platform connects 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.
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.
Analyze 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 analyzed for further insights.

HOW CAN NEXMO HELP?

Real time event data
The Nexmo 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.
The highest quality voice
The Nexmo platform connects directly to the Vonage MPLS network and to Tier 1 carriers that provide the highest quality voice services. In addition, with data centers 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 only pay 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
The Nexmo platform 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 significantly improves the quality of transcriptions so you can improve analysis and gain new insights.
All the insights you need
The Nexmo 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.

With Nexmo, we do not have 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 Nexmo
