CCIE Collaboration (active) with 21+ years of hands-on Cisco Unified Communications experience. I provide on-demand expert troubleshooting and escalation support for complex Cisco UC environments — working across multiple concurrent engagements daily.
This service provides expert diagnosis and resolution for complex Cisco UC issues — available hourly or as a block-of-hours retainer. I reproduce issues in lab, perform deep SIP trace analysis, and deliver root-cause findings with resolution steps.
Rate: $120/hr. Typical engagements range from 5 hrs (targeted issue diagnosis and resolution) to 20+ hrs (ongoing retainer for multi-issue environments). Scope and estimate provided before work begins.
Troubleshooting expertise includes:
• CUCM call routing, registration, and dial-plan failures
• CUBE / SBC SIP trace analysis and interop issues
• CUC voicemail integration and delivery failures
• Expressway and MRA traversal failures
• IM&P presence and federation issues
• UC security — certificate expiry, TLS handshake failures, SRTP issues
• UCCX call-flow and agent desktop problems
• Lab reproduction of complex issues before change windows
I work independently, communicate clearly, and deliver on schedule.
Available for: architecture engagements, deployment projects, troubleshooting/escalation retainers, and health-check audits.
