I wonder if someone could provide me with some advice.
I work for a small company that has 3 branches, all the branches are connected by a VPN.
At each branch we have an ancient BT Fusion system, with all the lines running over ISDN.
Would Asterisk let me scrap the old bt fusion and use a new dedicated pbx unit based on pc components.
If so, what hardware would be required.
Many thanks for your help
