Call-tracking

A call-tracking system, comprising:

• a sending circuit configured to forward from a first user equipment associated with a first telephone number a request for a web page to a web server host and forwarding a reply message from the web server host to the first user equipment;
• a receiving circuit configured to receive in response to the request, the reply message comprising the web page and at least one second telephone number associated with a second user equipment;
• a retrieving circuit configured to retrieve the first telephone number, the second telephone number, a time associated with the forwarding of the reply message to the first user equipment, and a service provider indicator for a service provider associated with the web server host;
• a storing circuit configured to store, associated with each other, in a first database the first telephone number, the second telephone number, the service provider indicator and the time associated with the forwarding of the reply message;
• a trigger receiving circuit configured to receive from a proxy server a trigger message comprising two telephone numbers, said trigger message indicating a telephone call related to the two telephone numbers;
• a first determining circuit configured to determine whether the two telephone numbers correspond to the first telephone number and the second telephone number stored associated with each other in the first database;
• a second determining circuit configured to, if the two telephone numbers correspond to the first telephone number and the second telephone number, determine, based on a time difference between the time associated with the forwarding of the reply message and a time indicative of when the telephone call was made, whether the call has been made within a predetermined time or predetermined time interval from the forwarding of the reply message;
• and,
• a call indicator configured to store information related to the call in the first database or a second database, if the call has been made within the predetermined time or predetermined time interval.

A call tracking system, comprising an HTTP proxy server and a Service Control Point, wherein the HTTP proxy server comprises:

• a sending circuit configured to forward from a first user equipment associated with a first telephone number a request for a web page to a web server host and forwarding a reply message from the web server host to the first user equipment;
• a receiving circuit configured to receive in response to the request, the reply message comprising the web page and at least one second telephone number associated with a second user equipment;
• a retrieving circuit configured to retrieve the first telephone number, the second telephone number, a time associated with the forwarding of the reply message to the first user equipment, and a service provider indicator for a service provider associated with the web server host;
• a storing circuit configured to store, associated with each other, in a first database the first telephone number, the second telephone number, the service provider indicator and the time associated with the forwarding of the reply message;
• a call indicator configured to store, in the first database or a second database, information related to a telephone call having been made between the first telephone number and the second telephone number within a predetermined time or predetermined time interval;
• a second sending circuit configured to send the first telephone number, the second telephone number, the service provider indicator and the time associated with the forwarding of the reply message to a third database;
• and
• a second receiving circuit for receiving from the Service Control Point a message comprising the first telephone number, the second telephone number and an indication that the telephone call has been made;
• the Service Control Point comprises:
• a trigger receiving circuit configured to receive from a proxy server a trigger message comprising two telephone numbers, said trigger message indicating a telephone call related to the two telephone numbers;
• the third database;
• a first determining circuit configured to determine whether the two telephone numbers correspond to the first telephone number and the second telephone number stored associated with each other in the third database;
• a second determining circuit configured to, if the two telephone numbers correspond to the first telephone number and the second telephone number, determine, based on a time difference between the time associated with the forwarding of the reply message and a time indicative of when the telephone call was made, whether the call has been made within the predetermined time or predetermined time interval from the forwarding of the reply message;
• and
• a message generator for generating and sending the message, if the telephone call related to the two telephone numbers correspond to the first telephone number and the second telephone number and has been made within the predetermined time or predetermined time interval.

A computer program product stored in a non-transitory computer readable medium for controlling an HTTP proxy server, the computer program product comprising software instructions which, when run on the HTTP proxy server, causes the HTTP proxy server to:

• forward from a first user equipment associated with a first telephone number a web request for a web page to a web server host,
• receive in response to the request, a reply message comprising the web page and at least one second telephone number associated with a second user equipment,
• forward the reply message to the first user equipment,
• retrieve the first telephone number, the second telephone number, a time associated with the forwarding of the reply message to the first user equipment, and a service provider indicator for a service provider associated with the web server host,
• store, associated with each other in a first database, the first telephone number, the second telephone number, the service provider indicator and the time associated with the forwarding of the reply message to the first user equipment,
• receive from a proxy server a trigger message comprising two telephone numbers, said trigger message indicating a telephone call related to the two telephone numbers,
• determine whether the two telephone numbers correspond to the first telephone number and the second telephone number stored associated with each other in the first database, and,
• if the two telephone numbers correspond to the first telephone number and the second telephone number, determine, based on a time difference between the time associated with the forwarding of the reply message and a time indicative of when the telephone call was made, whether the call has been made within a predetermined time or predetermined time interval from the forwarding of the reply message, and,
• if the call has been made within the predetermined time or predetermined time interval, store information related to the call in the first database or a second database.

A computer program product stored in a non-transitory computer readable medium for controlling a web server host, the computer program product comprising software instructions which, when run on the web server host, causes the web server host to:

• create and send a reply message to a call-tracking system for a request for a web page forwarded from a first user equipment associated with a first telephone number, said web page comprising at least one second telephone number;
• determine if there is in the forwarded request an information header with data indicating that a call from the first user equipment to a second user equipment associated with a second telephone number can be tracked by the call-tracking system;
• and
• add an HTTP header comprising the second telephone number to the reply message only if it has been determined that the information header is present in the request.
