The client required the interconnection of three of their Indian offices through a dedicated voice network, separate from their current data infrastructure. Highlighting enhanced security measures across the Application, Presentation, and Session layers of the network was deemed essential.

The main challenge was to create a separate voice network that smoothly integrated with the client's current infrastructure while implementing robust security measures. Additionally, the requirement for specific city-wise and international DIDs/Toll-Free Numbers increased complexity. This necessitated comprehensive addressing of security vulnerabilities, such as Denial of Service, Privacy breaches, and Fraud, to mitigate potential risks to revenue, productivity, customer experience, compliance, and brand reputation.

• Ensuring seamless integration of the voice network with existing infrastructure
• Managing the complexity of specific city-wise and international DIDs/Toll-Free Numbers
• Addressing security vulnerabilities comprehensively to mitigate risks
• Safeguarding against potential threats to revenue, productivity, customer experience, compliance, and brand reputation.

Viva addressed the client’s needs and provided them with Software-Defined Voice Networking (SDVN) with SBCaaS. The solution compromised of; Software-Defined Voice Networking (SDVN) Infrastructure:
