Have a Fire Department that needs a phone system installed.  Employees need to buz another in at the door.  The Visitor should pick up a phone and dial in to request entry.  Weather a speaker is installed or just a camera is to be determined.  Experienced Users only reply to this question please.  What phone system would benefit me the most or you are most comfortable with, without all the bells and whistles?  Please be specific.
You advice is greatly appreciated! ;)

    Asterisk is for company that has a dedicated IT department and whats VoIP based system. I have installed many PBX thruout many municpalities in NJ and California (including fire and police). The ability to buzz someone in requires typically dry relay contacts which Asterisk does not provide, you need seperate equipment to do so. Asterisk is a great system for VoIP and is relatively new, which means very few people no how to install.

    I would go with Avaya ACS (originally AT&T then Lucent), it has door contacts built in the main system processor. Addtionally the ACS can be programmed via remote, also the system can handle cordless phones out of the box, which is usually helpful when cleaning the trucks outside after a weekend "wet down".

    The ACS can handle up to 31 CO lines, T1 digital if needed and up to 41 phones, and probally is the most reliable system that I have ever installed over time. Also you can intergrate the ACS into a VoIP envirometn if you so choose later on using there new API card.

    What type of system are you replacing? How many users? How many lines?

    Kindest regards,
