Thanks in advance to anyone who takes the time to read this message and respond.
I am looking for a new phone system that will meet several criteria. Before I list what I am looking for, let me provide some brief background information.
We have 3 separate offices; each office will not have more than 10 phones and 5 in/outbound lines. We already have a basic VPN setup between all 3 offices, and each office has a broadband connection. Two of the offices are on a wireless (microwave I believe) connection and the third has DSL. The DSL is 768kb down and 256kb up; the two other facilities are both 512kb up and down.
What I would like is the following:
Each office location needs to make and receive calls in the same manner they do today, with both local and long-distance traffic (including 911 calls in case of emergency)
Each office will need the ability to transfer any incoming call to another office location seamlessly, and free up the incoming line
Need to intercom between all 3 offices, to anyone’s phone
Need to be able to smart-route calls from one office location to another if a user attempts to make an outbound call that would be cheaper to complete if originated from one of the other locations. For example, if the 3 areas are Los Angles, New York, and Dallas. If a user in Dallas attempted to make a call to a 3rd party in NY, I would want the system to recognize this, and originate the call to the outside party from the NY office.
Lastly, I need the ability to conference call between 2 or more offices and an outside number.
Is this something that VoIP can do?
What type of equipment should I be looking at assuming it could do this?
Without knowing the above, I started browsing at the Avaya IP Office:Small Office Edition. Am I on the right track?
