 ## 🔧 Recent Fixes & Improvements
 
+### PRODUCTION READY: Extension Transfer System Overhaul (September 2025) - FULLY RESOLVED
+Comprehensive overhaul of extension-based call transfers with enterprise-grade reliability.
+

+
+#### Client Name Generation Consistency Fix
+- **Critical Issue Fixed**: Inconsistent client naming between capability tokens and call acceptance

+  - Capability token generation
