Methods and apparatuses to track information using call signaling messages

摘要

Methods and systems to facilitate real time communications via a telephonic apparatuses that support data communications. In one embodiment, a telephonic apparatus includes: a network interface to submit a query over a data communication network and to receive a listing with embedded information about the query; and a call module coupled to the network interface, the call module to embed the information about the query in a call signaling message for a telephonic connection according to the listing.

主权项

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.
