Development of a Virtual Multi-Number Connectivity Platform for Residential Building Intercom Systems

Clients face limitations with single-assignment local phone numbers to building units, leading to inconveniences for residents and delivery services. The existing system only supports one phone number per unit, causing missed deliveries and communication issues, especially when residents share or change their contact numbers.

A mid-sized property management company managing numerous residential units seeking to improve intercom and communication systems.

• Create a scalable system enabling residents to generate and manage multiple local phone numbers linked to their units.
• Allow residents to subscribe and process recurring payments for phone number management services.
• Automate the assignment of new virtual phone numbers localized to specific cities or regions.
• Ensure secure delivery of generated phone numbers via email or messaging platforms.
• Implement high availability and fault-tolerance to maintain uninterrupted service during server or network failures.
• Provide a user-friendly interface for seamless number management, subscription handling, and configuration.

• User registration and secure login tailored for personalized account management.
• Subscription module allowing users to purchase and renew phone number management services.
• Automated creation of local, unique VoIP phone numbers for each user, supporting unlimited number generation within subscription limits.
• Call forwarding setup for each generated number to multiple user specified devices or locations.
• Call group management to handle multiple forwarding numbers as a unified call group.
• Integration with VoIP service providers to generate, configure, and manage local phone numbers dynamically.
• Secure email/message delivery of generated phone numbers and configuration details to users.
• Provision for creating safelists, such as intercom numbers, and associating them with user numbers for security and ease of access.
• Scalable architecture supporting high-volume usage with load balancing and redundancy.

• VoIP service provider APIs for dynamic number provisioning and call management
• Payment gateway API for subscription billing and transaction processing
• Email or messaging service API for secure delivery of generated numbers and notifications

• System scalability to support increasing user base with minimal latency
• High availability with 99.9% uptime SLA backup and fallover mechanisms
• Strong security protocols to ensure personal data and transaction security
• Fast response times with a target API latency below 200ms
• Secure data storage complying with data protection regulations

The implementation of this platform is expected to streamline communication management for residents, significantly reduce missed deliveries and communication failures, and enhance user satisfaction. The system aims to support hundreds to thousands of users concurrently with high reliability, leading to improved operational efficiency and customer experience in residential property management.
