1. A computer-implemented method, comprising:

  • receiving, by a server system over a data communication network, a query initiated as input by a user operating a telephonic apparatus;

    searching, by the server system, a database to identify a listing relevant to the query;

    encrypting, by the server system, tracking information about the query other than a telephone number to generate encrypted tracking information about the query;

    transmitting, by the server system over the data communication network, the listing and the encrypted tracking information about the query to the telephonic apparatus;

    receiving, by the server system, a call signaling message from the telephonic apparatus, wherein the encrypted tracking information about the query is embedded in the call signaling message;

    in response to receiving the call signaling message, facilitating, by the server system, a telephonic connection between the telephonic apparatus and a communication device corresponding to a callee identified by the listing; and

    extracting, by the server system, the encrypted tracking information about the query from the call signaling message and associating the telephonic connection with the tracking information about the query.
