System and method for routing calls if potential call paths are impaired or congested
First Claim
1. A method for routing a call over a packet network, said method comprising:
- receiving a call request from a calling party to call a called party at a network address;
determining at least one potential call path over a packet network to connect the calling party to the called party at the network address;
accessing network performance information associated with each potential call path;
determining that each of the call paths are impaired or congested; and
in response to determining that each of the call paths are impaired or congested, routing the call over a call path other than one of the at least one potential call paths to enable the calling party to communicate with the called party.

Abstract
A system and method for routing a call over a packet network. A call request may be received from a calling party to call a called party at a network address. At least one potential call path over a packet network may be determined to connect the calling party to the called party at the network address. Network performance information associated with each potential call path may be accessed and a determination may be made that each of the call paths are impaired or congested. In response to determining that each of the call paths are impaired or congested, the call may be routed over a call path other than one of the at least one potential call paths to enable the calling party to communicate with the called party.

7. A system for routing a call over a packet network, said system comprising:
-
an input/output (I/O) unit configured to communicate over a packet network;
a database configured to store network performance information of the packet network;
a processing unit in communication with said I/O unit and database, said processing unit configured to;
receive a call request from a calling party to call a called party at a network address;
determine at least one potential call path over a packet network to connect the calling party to the called party at the network address;
access, in said database, network performance information associated with each potential call path;
determine that each of the call paths are impaired or congested; and
in response to determining that each of the call paths are impaired or congested, route the call over a call path other than one of the at least one potential call paths to enable the calling party to communicate with the called party. - View Dependent Claims (8, 9, 10, 11, 12)
