I'm just getting started with this VoIP system. It's sweet by the way. I'm currently managing a ShoreTel VoIP system. It has a feature that we can assign any user to a phone without rebooting or changing a config file. Examples: 1. New user is added to system, he or she needs to be assigned to a phone. Can you assign the user to that phone without rebooting it or changing it by a web interface? I'm currently looking into using Cisco 7940/60 phones on some upcoming deployments. 2. Can the users reassign their extension to a different phone for a short period of time then send it back home to their primary phone?
