I am playing around with FreePBX. Actually I have an Cisco Callmanager and I plan to change vom Cisco to FreePBX.
A nice and very Important feature is the PickUp group.
Example: A Person is Calling the 231 and just this phone is ringing, but on all phones inside this Pickup group I can see who is calling and I can Pick-up the call from every phone inside the group.
Is this possible with FreePBX? Or is it depending on the SIP Phone?
