Introduction
In India's manufacturing sector, ensuring the security and integrity of transactions is crucial. As IT and Operations leaders, you understand the importance of multi-factor authentication (MFA) in preventing unauthorized access to sensitive information. Voice-based MFA offers a more secure and user-friendly experience, and in this playbook, we'll explore how to implement it in India, leveraging Zoho CRM and CRM Messaging to streamline your workflow and ensure compliance with VoIP India regulations.
Why Voice fits transactional Multi-factor Authentication
Voice-based MFA is gaining traction in India, particularly in the manufacturing sector, due to its ability to provide an additional layer of security without compromising user experience. Unlike SMS-based MFA, Voice-based MFA uses a phone call to deliver a one-time password (OTP) or authentication code, making it more secure and less prone to errors.
How the program works end-to-end in Zoho CRM + CRM Messaging
To implement Voice-based MFA in Zoho CRM, you'll need to set up a workflow that triggers a Voice call when a user attempts to access a sensitive area of your system. The user initiates a transaction, Zoho CRM triggers a workflow, and CRM Messaging delivers a one-time password (OTP) or authentication code to the user's phone. The user enters the OTP or authentication code to complete the transaction, and the workflow updates the user's contact fields in Zoho CRM.
Compliance notes for India
In India, compliance with VoIP India regulations is crucial. The Telecom Regulatory Authority of India (TRAI) requires all VoIP service providers to register with the Department of Telecommunications (DoT) and obtain a license to operate. VoIP service providers must also comply with TRAI's guidelines on unsolicited commercial communications, including provisions for obtaining user consent and providing an opt-out mechanism.
Cost considerations
The cost of implementing Voice-based MFA in India depends on several factors, including the number of users, the frequency of transactions, and the VoIP service provider. While the cost of Voice calls may be higher than SMS, the added security and user experience benefits can lead to significant improvements in security and user satisfaction.
Pros and cons
Here are the pros and cons of using Voice-based MFA in India:
- Higher security compared to SMS-based MFA
- Better user experience
- Less prone to errors
- Higher cost compared to SMS
