How long does it take to set up a call management software?

A cloud call management software can be set up anywhere between 2 to 3 hours. In fact, we helped Zerodha set up their call management system within 3 hours.

How does pricing work for the voice calls?

Exotel charges voice calls on a per-leg basis:

1. Inbound Calls - An Inbound call is a single-legged call ~ When a call lands on a customer-facing number, Exotel dials an agent number to connect the customer’s call.

2. Outbound calls - An Outbound call is a double-legged call ~ When an agent calls customer, Exotel first dials agent number and then dials the customer number to connect them over a virtual number.

How to choose the best OTP service provider in India?

Choosing a reliable OTP service provider in India is the key to implement a robust authentication system. Below are some of the important factors to consider:

1. Delivery and Latency Rates: Always choose a provider that can assure you of better OTP delivery rates and lower latency rates.​

2. Flexible APIs: If you are implementing an OTP authentication system using APIs, then make sure that your OTP service provider’s APIs are flexible and easy to implement in your backend systems.

3. Data Security: Your customers’ data should be your number one priority. Always choose a provider that is ISO certified and exercises enterprise-grade security practices.

4. Scalability: Always choose a provider that can quickly scale up or down according to your business needs.

Can I remove my business number from Truecaller's Spam list if I sign up for its Verified Business Caller ID?

The Verified Business Caller ID solution is not a spam removal solution rather is a brand

identity solution to ensure better identification, branding, and context to improve calling efficiency. It also helps prevent identity theft by scammers. The overall aim is to improve customer confidence and not to whitelist spam numbers. Crossing the spam threshold that is visible through an additional spam score tag on incoming call screens doesn't limit all the features offered as part of the solution.
