A system for identifying and interacting with callers originating from a wireless telephony and data network or from a tethered communications network, the system comprising: - a telephone switch (105, 110) for receiving and distributing an incoming call received from the wireless network to a routing target; - a server (116; 117) for executing a software routine for: receiving from the switch (105, 110) notification of the incoming call; identifying the incoming call as being from a wireless caller calling from the wireless network; if the incoming call is identified as being from a wireless caller calling from the wireless network, generating an automated short message service message to the wireless caller while the incoming call is waiting at the switch (105, 110); sending the SMS message over an SMS path; receiving a response SMS message back from the caller over the SMS path, the response SMS message including identification information for the wireless caller; retrieving additional data for the wireless caller from a customer database based on the identification information; and sending the retrieved additional data to the routing target over an interface in conjunction with routing of the incoming call by the switch (105, 110) to the routing target. - a telephone switch (105, 110) for receiving and distributing an incoming call received from the wireless network to a routing target; - a server (116; 117) for executing a software routine for: receiving from the switch (105, 110) notification of the incoming call; identifying the incoming call as being from a wireless caller calling from the wireless network; if the incoming call is identified as being from a wireless caller calling from the wireless network, generating an automated short message service message to the wireless caller while the incoming call is waiting at the switch (105, 110); sending the SMS message over an SMS path; receiving a response SMS message back from the caller over the SMS path, the response SMS message including identification information for the wireless caller; retrieving additional data for the wireless caller from a customer database based on the identification information; and sending the retrieved additional data to the routing target over an interface in conjunction with routing of the incoming call by the switch (105, 110) to the routing target. receiving from the switch (105, 110) notification of the incoming call; identifying the incoming call as being from a wireless caller calling from the wireless network; if the incoming call is identified as being from a wireless caller calling from the wireless network, generating an automated short message service message to the wireless caller while the incoming call is waiting at the switch (105, 110); sending the SMS message over an SMS path; receiving a response SMS message back from the caller over the SMS path, the response SMS message including identification information for the wireless caller; retrieving additional data for the wireless caller from a customer database based on the identification information; and sending the retrieved additional data to the routing target over an interface in conjunction with routing of the incoming call by the switch (105, 110) to the routing target.
