Abstract:
1. A computer-implemented method, comprising: processing, by a first server of a server system, a transmission corresponding to a query submitted via a telephonic apparatus over a data communication network; searching a database of the server system 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 for the telephonic apparatus; receiving, by a second server, 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 second server, a telephonic connection between the telephonic apparatus and a communication device corresponding to a callee identified by the listing; and extracting the encrypted tracking information about the query from the call signaling message and associating the telephonic connection with the tracking information about the query.
