Identifying a context for a call

A system for identifying a context for a call, said system comprising:

• a context inference server communicatively connected to a trusted telephone network;
• means for detecting a plurality of context clues for a call at said context inference server;
• and
• means for identifying a context for said call from said plurality of context clues.

A computer program product for identifying a context for a call, said computer program product comprising:

• a recording medium;
• means, recorded on said recording medium, for enabling detection of a plurality of context clues for a call;
• and
• means, recorded on said recording medium, for identifying a context for said call from said plurality of context clues.

A method for inferring a call context comprising:

• receiving a context request for a call;
• detecting context clues comprising at least one from among a line number, a line subscriber profile, an authenticated caller identity, an authenticated callee identity, a caller profile associated with said authenticated caller identity, a callee profile associated with said authenticated callee identity, a line number accessed for said call, and a geographical location served by switches processing said call;
• and
• inferring from said context clues at least one from among who is placing said call, who is receiving said call, at least one device utilized for said call, a location of said at least one device utilized for said call, a billing plan for said call, a path of said call, and a subject matter of said call.
