I've done PBX migrations with PBX-to-PBX integration between Cisco CUCM and Avaya PBX systems, Cisco CUCM and Mitel PBX systems, as well as between CUC and Vertical PBX systems. I've migrated Enterprise TDM trunks to carrier SIP trunking with Session-Border-Controller box-to-box redundancy (based on Cisco CUBE RG Infrastructure) solutions within a single data center as well as with site-to-site redundancy between SBCs installed in geographically dispersed data centers.
I've also deployed Cisco Nexus data center solutions and performed migrations from Cisco Catalyst switches in data centers to Cisco Nexus systems. I've developed collaboration strategies for Fortune 500 companies, designed and architected VoIP and WAN/LAN solutions for large enterprises, put together BOMs and Statements of Work, deployed VoIP, routing, and switching (including data center) solutions for large enterprises and medium-size businesses as well as for governmental agencies. I've also remediated existing VoIP, routing, and switching solutions for large enterprises and medium-size businesses and served as a top-level technical escalation point.
