What is VoIP and how can you use it in India?

VoIP stands for Voice over Internet Protocol. It is a technology that allows you to make and receive phone calls over the internet. However, in India, it is illegal to terminate VoIP calls on landline/PSTN phone lines and to use VoIP gateways. The only way to use VoIP in India is via App to App calling, or by using VoIP for international calls.

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 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 is a hosted contact centre software different from a traditional PBX or EPABX?

Compared to a traditional PBX system, the cloud telephony system allows you to pay for what you use, broadly through plans that suit business requirements or scale. Enterprises can talk to us (link below) for custom configurations to help large-scale teams engage better, or to support a host of use cases. All you need to get started with cloud telephony is a computer and internet connection.

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.

How does SMS API work?

The SMS API is a HTTP based REST API which allows you to trigger SMSes using actions/buttons at your internal application. An SMS API is something like a code that allows communication between one platform to another. Think of it as a friendship between two people, a bond is created and then knowledge or information is shared.
