I am looking for a highly skilled developer to enhance my legacy telephony system, developed in Visual Studio 6.0 (C/C#) on Windows XP. This system currently processes SIP-based phone calls through softphones, connects to a SQL Server backend, and includes a middleware component in C and C# (.NET).

Key Areas of Focus:

- Enhancing the system features

- Improving the SIP-based phone call processing

- Upgrading the integration capabilities with other systems

The ideal candidate should have:

- Strong expertise in legacy Windows environments

- Deep knowledge in telephony protocols

- Proficiency in .NET technologies

- Proven experience in modernizing and integrating older codebases

I value your ability to maintain the current system stability while pushing for these enhancements. Experience with SIP call processing is a plus. Your role will be pivotal in improving our telephony system's integration with other systems.
