Your complete guide to becoming a VoIP and Unified Communications Engineer. Design and manage modern communication systems that connect businesses worldwide.
VoIP (Voice over IP) and Unified Communications (UC) Engineers design, implement and maintain communication systems that enable voice calls, video conferencing, instant messaging and collaboration over IP networks. You'll work with technologies like SIP, PBX systems, Session Border Controllers (SBCs), and UC platforms like Microsoft Teams, Cisco Webex and Asterisk.
This role combines networking expertise with telecommunications knowledge. You'll configure IP phones, design call routing, implement security for voice traffic, ensure quality of service (QoS), troubleshoot call quality issues, integrate with PSTN and SIP trunks and manage enterprise communication platforms.
VoIP/UC Engineers are critical to modern business communications. As companies move away from traditional phone systems to cloud-based UC solutions, demand for these specialists continues to grow. This career offers excellent stability, specialized technical skills and opportunities in telecommunications, enterprises and managed service providers.
