CCIE Collaboration (active) with 21+ years of hands-on Cisco Unified Communications experience. I design, deploy, troubleshoot, and optimize Cisco CUBE (Cisco Unified Border Element) and Cisco SBC deployments for enterprise and mid-market clients — working across multiple concurrent engagements daily.
This service covers end-to-end Cisco CUBE / SBC SIP trunk architecture: dial-peer design, codec negotiation, early/delayed-offer configuration, HA box-to-box redundancy, and full carrier interoperability testing.

CUBE / SBC expertise includes:
• SIP trunk architecture and dial-peer configuration
