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 program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:

receiving a client copy of an audio file from a client device associated with a unified telephony call of a plurality of unified telephony calls within a unified telephony system;

comparing the client copy of the audio file to a local copy of the audio file using a reference algorithm;

determining 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;

associating a visual indicator with the quality of service, wherein the visual indicator includes a color associated with the quality of service associated with each client device associated with the unified telephony call;

transmitting the visual indicator to each client device associated with the unified telephony call;

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

if the quality of service falls below a threshold, establishing a failover connection to the unified telephony call using a different client device based upon, at least in part, the failover connection information received from the client device;

if the quality of service falls below the threshold, implementing a corrective measure; and

providing a visual display of a summary of overall quality of service for the unified telephony system including a quality of service associated with each of the plurality of unified telephony calls.

2. The computer program product 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 program product of claim 1, wherein the reference algorithm includes a Perceptual Evaluation of Speech Quality algorithm.

4. The computer program product of claim 1, 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.

5. The computer program product of claim 4, further comprising instructions for:

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.

6. A computing system including a processor and memory configured to perform operations comprising:

receiving a client copy of an audio file from a client device associated with a unified telephony call of a plurality of unified telephony calls within a unified telephony system;

comparing the client copy of the audio file to a local copy of the audio file using a reference algorithm;

determining 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;

associating a visual indicator with the quality of service, wherein the visual indicator includes a color associated with the quality of service associated with each client device associated with the unified telephony call;

transmitting the visual indicator to each client device associated with the unified telephony call;

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

if the quality of service falls below a threshold, establishing a failover connection to the unified telephony call using a different client device based upon, at least in part, the failover connection information received from the client device;

if the quality of service falls below the threshold, implementing a corrective measure; and

providing a visual display of a summary of overall quality of service for the unified telephony system including a quality of service associated with each of the plurality of unified telephony calls.

7. The computing system of claim 6, 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.

8. The computing system of claim 6, wherein the reference algorithm includes a Perceptual Evaluation of Speech Quality algorithm.

9. The computing system of claim 6, 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.
