The Voice Engineer owns design, implementation, and support/troubleshooting responsibility for a Cisco Collaboration environment, including on-premises platforms (CUCM, Cisco Unity Connection, Cisco Emergency Responder/CER) and their migration to Cisco Webex Calling and Webex Device Integration (Webex DI). This role is suited to a seasoned engineer with approximately 7–8 years of hands-on Cisco voice/UC experience, expected to independently design and implement migration and collaboration projects, configure and secure SIP trunking (TLS/SRTP, certificates), and provide structured support and troubleshooting across Cisco CUBE, Expressway, and Jabber environments. Working knowledge of third-party Session Border Controllers (Ribbon, Oracle Acme Packet, AudioCodes) for design, implementation, configuration, and troubleshooting is an added advantage. The role also requires strong customer handling and consistent adherence to defined processes for change, incident, and issue management.

SIP, Security & CUBE/SBC

• Cisco Emergency Responder (CER) and E911/emergency-calling configuration.

Webex Calling & Migration
