The admin UI was a poor stepchild (the UX developer was explicitly excluded from work on it). To implement "dial plans" and call routing, the product had a screen with sed style match and replacements. My involvement with the product started in the second product plan: a multi-tenant conferencing system in a 1U box, first at a startup, after the startup was acquired by Alcatel, Alcatel became Alcatel-Lucent, and finally when ANOTHER startup purchased rights to maintain the code as critical to their operations. In that final setting, I ended up in a room with about 30 customer service representatives, none of whom I could easily imagine had ever C.S. course. I expressed my amazement at their ability to deal with the reg-ex interface, and apologized the fact that they had to deal with an interface with such sharp edges!
