Abstract

A method, computer program product, and computer system for inferring quality of unified telephony calls based on real-time bi-directional exploitation of a full reference algorithm. A client copy of an audio file may be received from a client device associated with a unified telephony call. The client copy of the audio file may be compared to a local copy of the audio file using a reference algorithm. A quality of service associated with the client device may be determined based upon, at least in part, a difference between the client copy of the audio file and the local copy of the audio file.

Claims

1. A computer-implemented method comprising:

receiving, by a computing device, a client copy of an audio file from a client device associated with a unified telephony call;

comparing, by the computing device, the client copy of the audio file to a local copy of the audio file using a reference algorithm; and

determining, by the computing device, a quality of service associated with the client device based upon, at least in part, a difference between the client copy of the audio file and the local copy of the audio file.

2. The computer-implemented method of claim 1, wherein:

receiving the client copy of the audio file includes receiving a first client copy of the audio file from the client device at a first time, and receiving a second client copy of the audio file from the client device at a second time; and

wherein comparing the client copy of the audio file to the local copy of the audio file includes comparing first client copy of the audio file to the local copy of the audio file, and comparing the second client copy of the audio file to the local copy of the audio file.

3. The computer-implemented method of claim 1, wherein the reference algorithm includes a Perceptual Evaluation of Speech Quality algorithm.

4. The computer-implemented method of claim 1, further comprising:

associating a visual indicator with the quality of service; and

transmitting the visual indicator to one or more client devices associated with the unified telephony call.

5. The computer-implemented method of claim 4, wherein:

if the quality of service is above a first threshold indicating a relatively high quality, the visual indicator is indicative of a high quality of service;

if the quality of service is below a second threshold indicating a relatively low quality, the visual indicator is indicative of a low quality of service; and

if the quality of service is below the first threshold indicating the relatively high quality and above the second threshold indicating the relatively low quality, the visual indicator is indicative of a medium quality of service.

6. The computer-implemented method of claim 5, further comprising transmitting the visual indicator to a second client device associated with a moderator.

7. The computer-implemented method of claim 5, further comprising:

if the visual indicator is indicative of a low quality of service, transmitting a notification to the client device identifying a problem associated with the unified telephony call.

8. The computer-implemented method of claim 1, further comprising, if the quality of service falls below a threshold implementing a corrective measure.

9. The computer-implemented method of claim 7, further comprising:

receiving, from the client device, failover connection information prior to joining the unified telephony call; and

wherein implementing the corrective measure includes establishing a failover connection based upon, at least in part, the failover connection information.

10-23. -23. (canceled)

24. A computer-implemented method comprising:

receiving, by a computing device, a copy of an audio file associated with a unified telephony call from a client device during the unified telephony call;

determining, by the computing device, a quality of service associated with the client device, wherein the quality of service is determined based upon, at least in part, comparing the copy of the audio file received from the client device and a locally stored copy of the audio file using a full reference algorithm; and

if the quality of service falls below a threshold, executing, by the computing device, a corrective measure.

25. A computer-implemented method comprising:

receiving, by a computing device, a copy of an audio file associated with a unified telephony call from a client device during the unified telephony call;

determining, by the computing device, a quality of service associated with the client device, wherein the quality of service associated with the client is determined based upon, at least in part, comparing the copy of the audio file received from the client device and a locally stored copy of the audio file using a full reference algorithm;

determining, by the computing device, a quality of service of the unified telephony call based upon, at least in part, the quality of service associated with the client device; and

transmitting, by the computing device, at least one of the quality of service associated with the client device, the quality of service of the unified telephony call, and a status of a unified telephony infrastructure to one or more client devices associated with the unified telephone call.
