How much does it cost to build an on-premise communication platform like Nucleus?

Costs depend on the features: messaging, WebRTC calls, SIP integration, SMS, mobile apps, task tracking, and on-prem deployment. We provide a tailored estimate after reviewing your scope.

Is SIP calling difficult to integrate?

It requires careful backend setup, but we've successfully implemented SIP so users can place and receive standard phone calls directly in the platform.

Can you add task management or workflow tools to chat messages?

Yes. Nucleus supports task creation from messages, to-do lists, progress tracking, and can be extended with custom workflows or automation.

Can you build mobile apps for iOS and Android?

Yes. Native apps can replicate full platform functionality: chat, tasks, WebRTC, SIP calls, push notifications, and secure session handling.
