I've been tasked with implementing a Cisco VOIP system and I need some input on what hardware I need to purchase. This is my first foray into VOIP, so I really appreciate any help you can offer.
We have about 60-70 users currently, and we'll probably need to plan for at most 100 users, including remote users. We would like the ability to write our own custom apps for the phones, as well as have some call management features like a call attendant.
In my research, I've come across the "Unified Communications Manager Express" and the "Unified Communications Manager Business Edition." Can anyone tell me which one would be the best for my environment? We need all the basic phone functionality -- voice mail, conference calling, call forwarding, etc. Plus we'd like to be able to write our own phone plug-ins and have a call attendant application.
Thanks in advance!!
