As a dedicated Information Technology Professional, I have over 11 years of experience in Enterprise Voice and Networking. My expertise lies in Cisco Call Manager, where I have expanded my knowledge from version 6.X to 14.X. I have successfully upgraded/migrated different sites to newer platforms of CUCM and Unity with little to no impact on site. Ensuring that the call flow was working, I tested each possible way a call could get to its destination. With businesses pushing towards cloud technology, I have also started to build my knowledge in Cisco Webex Calling to create a go-anywhere phone system that leverages the cloud.
My experience spans various platforms of ESXi from version 5.X to 7.X, using the necessary tools to optimize UC platforms. I have worked on numerous levels of projects ranging from small office BE4K/CME, Multi-County multi-cluster deployments, UC environment IP changes, dial plan implementation/changes/fixes, SIP implementation, and complete system rebuilds. I have the ability to adapt to customer needs and ensure their satisfaction with my work.
Through testing sites, I have gained a deep understanding of PRI, Carrier SIP, MGCP, SIPREC, SCCP, SIP, and dial-peers. Debugging different protocols has helped me quickly come to solutions with practice, follow call flows, and deal with digit manipulation.
I also have experience in network deployments, from core build-outs, ASA configurations, to remote site IPSEC VPN connections. I have worked with different routing protocols, such as EIGRP, BGP, and OSPF, and leveraged prefix lists to re-inject static routes into other protocols.
With my experience, I am confident in my ability to provide expert solutions to any UC or networking issues while ensuring customer satisfaction.
