ABSTRACT:
A system and method can enable a user of a communications network, such as a Public Switched Telephone Network (PSTN), wireless and/or voice over IP network to participate in Presence Availability Management (PAM) and Instant Messaging (IM) activities of a PAM/IM network. In response to phone network triggers, a phone network Service Control Point (SCP) can generate requests to a web server. The web server can translate the requests to presence information that can be forwarded to presence user agents for participants of the PAM/IM network. The presence user agents can present the user's presence information to participants having the user on their “buddy list”. In turn, the presence user agent for the user can forward the presence information for participants on the user's “buddy list” to a media server that can communicate the information to the user through Automatic Speech Recognition, Text to Speech and/or Dual Tone MultiFrequency technology.
