Real-time monitoring of perceived quality of packet voice transmission

An apparatus comprising:

• a transceiver comprising:
• a packet interface configured to:
• couple to a packet switched network;
• and
• process packet headers of a call over the packet switched network to obtain packet transmission statistical data;
• a codec configured to:
• receive a coded digital signal for the call from the packet interface;
• and
• decode and decompress the coded digital signal to create a digital audio signal;
• a quality analyzer of the transceiver configured analyze at least one of the packet transmission statistical data or the digital audio signal to obtain a quality measurement for the call over the packet switched network.

A method comprising:

• receiving a call over a packet switched network at a packet interface;
• processing packet headers of the call to obtain packet transmission statistical data;
• receiving a coded digital signal for the call at a codec from the packet interface;
• decoding and decompressing the coded digital signal with the codec to create a digital audio signal;
• and
• analyzing at least one of the packet transmission statistical data or the digital audio signal with a quality analyzer to obtain a quality measurement for the call over the packet switched network.

A tangible computer readable medium having instructions stored thereon that, in response to execution by a computing device, cause the computing device to perform operations comprising:

• receiving a call over a packet switched network at a packet interface;
• processing packet headers of the call to obtain packet transmission statistical data;
• receiving a coded digital signal for the call at a codec from the packet interface;
• decoding and decompressing the coded digital signal with the codec to create a digital audio signal;
• and
• analyzing at least one of the packet transmission statistical data or the digital audio signal with a quality analyzer to obtain a quality measurement for the call over the packet switched network.
