A method and apparatus are disclosed for routing calls over an organization's private network 305 of private branch exchanges 304-1 to 304-P. In particular, when a member of the organization (e.g., an employee, etc.) places a call from his or her affiliated off-premises telecommunications terminal 301 (e.g., cell phone, etc.), the call is automatically routed to its destination through at least a portion of the private network of private branch exchanges (PBX's) when doing so reduces the cost of the call. In the illustrative embodiment, the call routing is performed automatically and transparently via software on the affiliated terminals (i.e., employees' cell phones) and on the organization's private branch exchanges such that in response to user input for placing a call to a public terminal, a second call is instead placed from the terminal to one of the plurality of associated PBX's. The call from the affiliated terminal to the PBX thus incurs no more cost than a call from the terminal to any other of the plurality of PBX's. |
