1. A method for routing a call to a called party number, comprising:
- determining that the call is subject to a predetermined type of routing, based on an origination identifier; and
based on the determination, transmifting instructions to route the call to a designated switch at which call traffic is aggregated and routed over a private trunk group,wherein the designated switch routes calls based on automatic selection of facilities-remote tie-line (ASF-RTL) routing.

Abstract
A method and system include routing telephone calls from multiple private networks via public lines and trunks in a public switched telephone network (PSTN) to a host switch, at which the connections would begin to run parallel. The host switch routes the telephone calls via a private trunk group to a private facility, such as an electronic tandem network (ETN) node or an asynchronous transfer mode (ATM) switch. If the private trunk group is full or unavailable, the host switch routes the telephone calls over alternate private or public trunk groups and selected carriers.

2. A method for routing a call to a called party number, comprising:
-
determining that the call is subject to a predetermined type of routing, based on an origination identifier; based on the determination, transmitting instructions to route the call to a designated switch at which call traffic is aggregated and routed over a private trunk group; and changing a called party identifier from a first number, corresponding to the called party number, to a second number, corresponding to an identifier of the designated switch. - View Dependent Claims (3, 4)

6. A method for routing a call to a called party number, comprising:
-
determining that the call is subject to a predetermined type of routing, based on an origination identifier; and based on the determination, transmitting instructions to route the call to a designated switch at which call traffic is aggregated and routed over a private trunk group, wherein the designated switch is associated with a private network associated with the called party number, the origination identifier is associated with the private network, and the call is routed over a public switched telephone network (PSTN) prior to determining that the call is subject to the predetermined type of routing.

7. A network device that provides instructions for routing a call to a called party number, wherein the network device
determines that the call is subject to a predetermined type of routing, based on an origination identifier, and based on the determination, the network device transmits instructions to route the call to a designated switch at which call traffic is aggregated and routed over a private trunk group, wherein the designated switch routes calls based on automatic selection of facilities-remote tie-line (ASF-RTL) routing.

8. A network device that provides instructions for routing a call to a called party number, wherein the network device
determines that the call is subject to a predetermined type of routing, based on an origination identifier, based on the determination, the network device transmits instructions to route the call to a designated switch at which call traffic is aggregated and routed over a private trunk group, and the network device changes a called party identifier from a first number, corresponding to the called party number, to a second number, corresponding to an identifier of the designated switch.
-
12. A network device that provides instructions for routing a call to a called party number, wherein the network device
determines that the call is subject to a predetermined type of routing, based on an origination identifier, and based on the determination, the network device transmits instructions to route the call to a designated switch at which call traffic is aggregated and routed over a private trunk group, wherein the designated switch is associated with a private network associated with the called party number, the origination identifier is associated with the private network, and the call is routed over a public switched telephone network (PSTN) prior to determining that the call is subject to the predetermined type of routing.

13. A computer-readable medium comprising an executable program for routing a call to a called party number, the program comprising:
-
routing determination code that determines that the call is subject to a predetermined type of routing, based on an origination identifier; and instruction transmission code that, based on the determination, transmits instructions to route the call to a designated switch at which call traffic is aggregated and routed over a private trunk group, wherein the designated switch routes calls based on automatic selection of facilities-remote tie-line (ASF-RTL) routing. - View Dependent Claims (17)

14. A computer-readable medium comprising an executable program for routing a call to a called party number, the program comprising:
-
routing determination code that determines that the call is subject to a predetermined type of routing, based on an origination identifier; instruction transmission code that, based on the determination, transmits instructions to route the call to a designated switch at which call traffic is aggregated and routed over a private trunk group; and code that changes a called party identifier from a first number, corresponding to the called party number, to a second number, corresponding to an identifier of the designated switch. - View Dependent Claims (15, 16)
