I'm working on a data synchronization package at my job using Microsoft SSIS to combine data from different application. We are using Cisco call manager and Unity for our phone system, and I'd like to access the Unity database to grab the phone extension for each employee. We chose the Unity database because some employees have a direct extension, some have voicemail and some have boss groups, and Unity seems to be the one database that records this information in an easy-to-access manner.
What I'm wondering (and I haven't been able to get an official answer as of yet) is if I can add a user to the Unity database without harming anything. I don't want to use the regular user, as I only need to read two columns in one database and having more access than that is too much of a vulnerability.
