An example apparatus is provided that receives a first message following conclusion of a voice call between a first apparatus and a second apparatus over a network. And in response to the first message, the apparatus obtains a geographic location of at least the first apparatus, and prepares a second message for transmission to the first apparatus. The second message includes a telephone number of a quality server to enable the first apparatus to initiate a voice call to the telephone number to participate in a voice quality test with the quality server, where the voice quality test includes calculation of a score reflecting a quality of the voice call. The apparatus receives the score, and correlates the score with the geographic location of at least the first apparatus and other network parameters obtained during the test to facilitate tuning the network based on the score and the geographic location.
