Abstract
Before completing a call initiated at a calling telephony device for a called telephony device; caller identification information for the calling telephony device is obtained for the call. If standard caller identification information is not available, the caller is prompted to provide spoken caller identification information. The caller identification information is communicated to the called telephony device via a connectionless protocol such as VoIP where a continuing connection does not exist between communicating end points. The called party is given call disposition options. The process which controls this operation may be located anywhere in the network, including at switching equipment and at the called telephony device.
