A unified communications engineer creates comprehensive communications systems for companies. This process may involve merging email, phone lines, and voicemail into a single system for internal use. In this role, you determine the needs of your employer, analyzing the use of each communication line. You then collaborate with other engineers to determine how to best integrate the systems together. To streamline the process, you may may need to install new hardware, upgrade current software, and train employees on how to utilize the new system. Other job duties include monitoring the system to ensure it works properly and troubleshooting any issues that arise.
