A system and method for providing identifying information about the source of an incoming communication to a mobile device is provided. An incoming communication is received by an enterprise network and a connection is established to the mobile device. A DTMF message is sent to the mobile device by the enterprise network. If the source of the incoming communication has an enterprise-assigned number then the DTMF message comprises an identifying key corresponding to the key field of a profile list comprising enterprise-assigned numbers and an identifying information entry for each enterprise-assigned number in the list. If the source of the incoming communication does not have an enterprise-assigned number, the DTMF message comprises an identifying number for the source of the incoming communication. If DTMF is not available on the mobile device, similar logic may be employed using, for example, ANI manipulation.
