What is the main difference between the two downloads? What are the limitations of the AsteriskNow Software PBX? We are a Avaya/Nortel and ESI shop, but have seen some recent RFPs out wanting to use open source telephony.

In the school system setting we have seen the Asterisk platform as the communications solution for phones (Digium mainly) as well as the intercom system including an interface for activation of speakers as well as a full blown bell schedule with insertion of wav files and pre-loaded prompts. Would the AsteriskNow software allow for the bell schedule functionality?

Any input or discussion would be greatly appreciated.
