Voice over internet protocol (voip) call quality

Abstract

A method for improving Voice over Internet Protocol (VoIP) call quality is disclosed. The method includes detecting, at a first computing device, a delay in receiving content data during a first media exchange. The first media exchange uses a first port. The method further includes automatically selecting a second port. The method also includes sending a port change notification featuring a port number of the second port to a second computing device. In some embodiments, the method further includes initiating a second media exchange using the second port.

What is claimed is: 
     
         1 . A method for improving Voice over Internet Protocol (VoIP) call quality, the method comprising:
 detecting, at a first computing device, a loss in receiving content data during a first media exchange, wherein the first media exchange uses a first port;   selecting, by the first computing device, a second port upon the detection of the loss that meets or exceeds a loss threshold;   sending a port change notification featuring a port number of the second port to a second computing device; and   initiating a second media exchange using the second port, wherein the second port is different from the first port.   
     
     
         2 . The method of  claim 1 , further comprising:
 sending a first media exchange termination notification and terminating the first media exchange.   
     
     
         3 . The method of  claim 1 , further comprising:
 initiating a first Session Initiation Protocol (SIP) signaling session to initiate the first media exchange; and   initiating a second SIP signaling session.   
     
     
         4 . The method of  claim 1 , wherein detecting the loss in receiving content data comprises detecting a packet loss. 
     
     
         5 . The method of  claim 4 , wherein detecting the packet loss comprises detecting the packet loss within a predetermined time window. 
     
     
         6 . The method of  claim 1 , wherein selecting the second port comprises randomly selecting the port number from a set range of port numbers. 
     
     
         7 . The method of  claim 1 , wherein the first media exchange and the second media exchange comprise an exchange of Real-time Transport Protocol (RTP) packets. 
     
     
         8 . A non-transitory, computer-readable medium storing a set of instructions that, when executed by a processor, cause:
 detecting, at a first computing device, a loss in receiving content data during a first media exchange, wherein the first media exchange uses a first port;   selecting, by the first computing device, a second port upon the detection of the loss that meets or exceeds a loss threshold;   sending a port change notification featuring a port number of the second port to a second computing device; and   initiating a second media exchange using the second port, wherein the second port is different from the first port.   
     
     
         9 . The non-transitory, computer-readable medium of  claim 8 , storing a set of further instructions that, when executed by the processor, cause:
 sending a first media exchange termination notification and terminating the first media exchange.   
     
     
         10 . The non-transitory, computer-readable medium of  claim 8 , storing a set of further instructions that, when executed by the processor, cause:
 initiating a first Session Initiation Protocol (SIP) signaling session to initiate the first media exchange; and   initiating a second SIP signaling session.   
     
     
         11 . The non-transitory, computer-readable medium of  claim 8 , wherein detecting the loss in receiving content data comprises detecting a packet loss. 
     
     
         12 . The non-transitory, computer-readable medium of  claim 11 , wherein detecting the packet loss comprises detecting the packet loss within a predetermined time window. 
     
     
         13 . The non-transitory, computer-readable medium of  claim 8 , wherein selecting the second port comprises randomly selecting the port number from a set range of port numbers. 
     
     
         14 . The non-transitory, computer-readable medium of  claim 8 , wherein the first media exchange and the second media exchange comprise an exchange of Real-time Transport Protocol (RTP) packets. 
     
     
         15 . A system for improving Voice over Internet Protocol (VoIP) call quality, the system comprising:
 a processor;   a memory operatively connected to the processor and storing instructions that, when executed by the processor, cause:   detecting, at a first computing device, a loss in receiving content data during a first media exchange, wherein the first media exchange uses a first port;   selecting, by the first computing device, a second port upon the detection of the loss that meets or exceeds a loss threshold;   sending a port change notification featuring a port number of the second port to a second computing device; and   initiating a second media exchange using the second port, wherein the second port is different from the first port.   
     
     
         16 . The system of  claim 15 , wherein the memory stores further instructions that, when executed by the processor, cause:
 sending a first media exchange termination notification and terminating the first media exchange.   
     
     
         17 . The system of  claim 15 , wherein the memory stores further instructions that, when executed by the processor, cause:
 initiating a first Session Initiation Protocol (SIP) signaling session to initiate the first media exchange; and   initiating a second SIP signaling session.   
     
     
         18 . The system of  claim 15 , wherein detecting the loss in receiving content data comprises detecting a packet loss. 
     
     
         19 . The system of  claim 18 , wherein detecting the packet loss comprises detecting the packet loss within a predetermined time window. 
     
     
         20 . The system of  claim 15 , wherein selecting the second port comprises randomly selecting the port number from a set range of port numbers.
