  • Multi-database integration across MongoDB, MySQL, and PostgreSQL
  • Visual workflow builder support for low-code journey configuration
Decision Engine Development

Telephony Call Handling

Asterisk-based telephony layer configured for voice scenarios, from voicemail to interactive customer journeys.
  • Multi-step interactive call routing scenarios
  • Voicemail flows for missed and overflow calls
  • Dialplan logic for queuing and call transfer
  • Cross-channel interaction handoff between agents and queues
Telephony Call Handling

Voice-Ready Cloud Infrastructure

AWS infrastructure designed specifically for SIP traffic and call-handling workloads at production scale.
  • Autoscaling groups tuned for call volume patterns
  • SIP-aware load balancing through Kamailio
  • Dynamic Route 53 updates via AWS CDK
  • Custom AMI images built with Packer for predictable deployments
Voice-Ready Cloud Infrastructure

Performance Validation

A testing layer covering both the decision engine and the infrastructure that runs it under realistic conditions.
  • Load tests for peak call traffic on EC2 instances
  • Jest coverage for engine logic and decision paths
  • WebSocket tests for realtime monitoring and event flows
  • Comparative benchmarking across instance types under simulated SIP loads

Solution #1

Kamailio replacement of AWS NLB for protocol-aware voice traffic distribution.
Challenge #2
Manual DNS updates slowed scaling.
Solution #2

AWS CDK automation of Route 53 records inside the deployment pipeline.
Challenge #3
Inconsistent server state on launch.

Clients say

Incora has been great at understanding our company and the work we want to do. They took the time to understand who we were and didn’t rush or make suggestions that didn’t make sense. They keep delivering what they promise and are very helpful and easy to work with — there haven't been any complications. I don't think there's anything they can improve on — they’re getting better and better over time. Just tell them what you want, and they'll try to work around your expectations.
