VOICE OVER INTERNET PROTOCOL (VOIP) CALL QUALITY
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.
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.
