Instant Voice Bot Deployment and Maintenance-Free Experience: Optimize your Workforce and Enhance Call Outcomes with Real-Time Voice Streaming Technology

What is Voice Streaming?

Voice streaming allows you to broadcast calls in real-time in a single (unidirectional) or two-way flow (bidirectional). Unidirectional streaming enables to transcribe and monitor call quality in real time. Bidirectional streaming enables you to build intelligent conversational bots that will help you optimise your workforce and call outcomes.

Deploy your bots on the cloud

Setup your Voice AI Bots in a jiffy on the cloud

What’s wrong with deploying my bots on-premise?

Nothing wrong. Your voice bots will work just fine. But, you will have to deal with these shortcomings: 

• Complex custom integrations with on-premise telephone systems

• Poor compatibility with existing telephony infrastructure

• Stretched-out deliveries due to complex telephony infra

• STD code restrictions, downtimes, low pickup rates, connectivity issues and latency. 


Tune your bots to be more human-like

Latency or lag is a voice bot's worst enemy; naturally flowing speech is one of the most significant success factors for a voice bot to sound more human-like. 

Exotel’s high-performance APIs ensure an average latency of just 300 milliseconds, allowing for an accurate human-like conversation with your customers. 


Takes a quarter to deploy your voice bots?

The minimum time right now to deploy a POC is 3 months for any Voice Bot company. Drawn out delivery timelines are people,  operations and cost intensive as well, owing to complex custom integrations and compatibility issues with existing telephony infrastructure.

There are two types of Streams - Unidirectional and Bidirectional                                  

Unidirectional Streams allow you to Stream live calls over Websocket in a single direction, from Exotel to the WebSocket Endpoint. Some of the use cases for this are live transcription, real time monitoring of agents, real-time coaching, etc.              

Bidirectional Streams allow two-way flow of voice data over a Websocket. Exotel would send the voice data of the caller to a websocket endpoint. The endpoint can return voice data back on the websocket and Exotel would play it out to the caller. The primary use case for this is to enable building intelligent conversational bots that will help you optimize your workforce.


As a bi-directional stream’s major use case is a conversational bot so Voicebot is more appropriate. 

The voice bot applet can be plugged into the flow to replace the agent. As soon as the flow is hit, the voice bot applet will trigger a WebSocket connection with the URL endpoint. Once the connection is established, there will be real-time transmission/streaming of the audio in the same connection.

For instance, It can act as a conversational IVR bot, for example, in a stock trading company where the bot can ask for the name of the stock. The customer says the name and the bot can tell the real-time price of it.


There are two legs: 

- PSTN leg

- Voicebot leg

It can act as a conversational IVR bot, for example, in a stock trading company where the bot can ask the name of the stock. The customer says the name and the bot can tell the real-time price of it.
