Systems and methods for adjusting carrier quality metrics for intrinsic impariments
First Claim
1. A method of identifying a telephony carrier that is providing an unacceptable level of call quality when terminating calls to a group of telephone numbers, comprising:
- determining a quality of telephone calls that are placed to the group of telephone numbers via a first telephony carrier for a first period of time;
determining a quality of telephone calls that are placed to the group of telephone numbers via a second telephony carrier for a second period of time;
determining a threshold level of acceptable quality for calls placed to the group of telephone numbers based on the determined quality of the telephone calls placed via the first and second telephony carriers; and
identifying a telephony carrier as providing an unacceptable level of quality if a quality of calls placed to the group of telephone numbers by that carrier falls below the determined threshold level.

Abstract
An Internet protocol (IP) telephony system terminates calls to certain groups of telephone numbers via multiple different telephony carriers. The IP telephony system will discontinue using a telephony carrier to terminate calls if the quality provided by the carrier falls below a threshold level. The IP telephony system includes a quality monitoring unit that determines when a particular group of telephone numbers are intrinsically impaired, such that no carrier could provide high quality when terminating calls to those numbers. In these circumstances, the IP telephony system adjusts the quality threshold to which a carrier'"'"'s quality is compared when completing calls to the impaired numbers to account for the intrinsic impairment of the telephone numbers.

12. A system for identifying a telephony carrier that is providing an unacceptable level of call quality when terminating calls to a group of telephone numbers, comprising:
-
a call quality measuring unit that is configured to determine a quality of telephone calls that are placed to the group of telephone numbers via a first telephony carrier for a first period of time and a quality of telephone calls that are placed to the group of telephone numbers via a second telephony carrier for a second period of time; a threshold quality setting unit that is configured to determine a threshold level of acceptable quality for calls placed to the group of telephone numbers based on the determined quality of the telephone calls placed via the first and second telephony carriers; and a quality alert unit that is configured to identify a telephony carrier as providing an unacceptable level of quality if a quality of calls placed to the group of telephone numbers by that carrier falls below the determined threshold level. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
