Cost-conscious telecommunications terminal
View Patent ↗A method and apparatus are disclosed for routing calls over an organization's private network of private branch exchanges. 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 (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 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.
1. A method comprising:
receiving by a telecommunications terminal an input for placing a first call to a destination D;
selecting by said telecommunications terminal, based at least partially on an entry point through which said telecommunications terminal connects to a network, one of a plurality of associated private branch exchanges; and
placing by said telecommunications terminal, in response to said input, a second call to the selected private branch exchange;
wherein a call from said telecommunications terminal to the selected private branch exchange incurs no more cost than a call from said telecommunications terminal to any other of said plurality of associated private branch exchanges.
2. The method of claim 1 wherein said second call is directed to a telephone number that is in the address space of the selected private branch exchange and that is not associated with any telecommunications terminal.
3. The method of claim 2 wherein said telephone number is for establishing a connection to a destination that is specified during a call to said telephone number.
4. The method of claim 3 further comprising transmitting by said telecommunications terminal to the selected private branch exchange an identifier that identifies said destination D.
5. The method of claim 4 wherein said identifier is a telephone number that is not in the address space of any of said plurality of associated private branch exchanges.
6. The method of claim 3 wherein said connection traverses a path that comprises one or more of said plurality of associated private branch exchanges.
7. A method comprising:
receiving by a telecommunications terminal an input for placing a first call to a destination D;
selecting by said telecommunications terminal, based at least partially on what network said telecommunications terminal is connected to, one of a plurality of associated private branch exchanges; and
placing by said telecommunications terminal, in response to said input, a second call to the selected private branch exchange;
wherein a call from said telecommunications terminal to the selected private branch exchange incurs no more cost than a call from said telecommunications terminal to any other of said plurality of associated private branch exchanges.
8. A method comprising:
receiving by a telecommunications terminal an input for placing a first call to a destination D;
receiving by said telecommunications terminal an identifier from a wireless base station;
selecting by said telecommunications terminal, based at least partially on said identifier, one of a plurality of associated private branch exchanges; and
placing by said telecommunications terminal, in response to said input, a second call to the selected private branch exchange;
wherein a call from said telecommunications terminal to the selected private branch exchange incurs no more cost than a call from said telecommunications terminal to any other of said plurality of associated private branch exchanges.
9. A method comprising:
receiving by a telecommunications terminal an input for placing a first call to a destination D;
selecting by said telecommunications terminal, based at least partially on the geo-location of said telecommunications terminal, one of a plurality of associated private branch exchanges; and
placing by said telecommunications terminal, in response to said input, a second call to the selected private branch exchange;
wherein a call from said telecommunications terminal to the selected private branch exchange incurs no more cost than a call from said telecommunications terminal to any other of said plurality of associated private branch exchanges.
10. A method comprising:
receiving by a telecommunications terminal an input for placing a first call to a destination D;
selecting by said telecommunications terminal, based at least partially on the calendrical time at said telecommunications terminal, one of a plurality of associated private branch exchanges; and
placing by said telecommunications terminal, in response to said input, a second call to the selected private branch exchange;
wherein a call from said telecommunications terminal to the selected private branch exchange incurs no more cost than a call from said telecommunications terminal to any other of said plurality of associated private branch exchanges.
