**Legacy Telephony System Enhancement & Integration**
€12-18 EUR / 時間
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.
