Project description:
"I already have an in-house VoIP solution in progress—a SIP server built with ASP.NET /C# and a cross-platform softphone written in .NET MAUI. The core functionality is there, but it is not yet production-ready. I need someone who can step in, review the existing codebase, and see the whole project through to a stable, polished release.

Key objectives
• Resolve all stability and performance issues so calls remain reliable under load and the server maintains low-latency connections.
• Refactor and streamline the code for efficiency and long-term maintainability.
• Refresh the mobile UI with improved navigation, a modern design, and effortless responsiveness across iOS and Android form factors.
• Add the extra features and workflow enhancements still on our backlog (I’ll walk you through the priority list during onboarding).
• Produce clean, well-commented source and deployment-ready builds for both server and mobile clients.

I will give you full access to the current repository, test accounts, and usage scenarios. Once the fixes and upgrades are complete, the solution should install cleanly, pass my functional tests, and be ready for everyday use by our staff without crashes or call drops.

If you have proven experience with VoIP, SIP, ASP.NET, C#, and .NET MAUI, let’s discuss timelines and the best path to the finish line." (client-provided description)
