Abstract
A method of managing a communications network, managing secure transactions conducted by digital communications devices over a communications network and computer program product therefore. A Back to Back User Agent (B2BUA), for example, receives numerical input from a networked digital communications device, e.g., a Session Initiation Protocol (SIP) device, and determines when and whether the SIP device displays digits entered at the devices. The B2BUA analyzes received digits for an identification (ID) code and selectively couples the SIP devices with a media server capable of providing prompting the SIP devices. In cooperation with the media server, the B2BUA directs replacing sensitive codes (e.g., passwords or Personal Identification Number (PIN)) with placekeepers or suppressing display altogether. After sensitive code input is complete, digit entry display resumes.
