Abstract
In providing an information assistance service in a call by a user, the context of the call is ascertained. Context information is derived from information exchanges during the call.

Pertinent advertisements, which may be further individualized based on personal preferences, are provided to the user at the conclusion of the call, or otherwise transmitted to the user via voicemail, SMS, email, WAP, paging, facsimile, instant messaging, text messaging, picture phone, video phone, etc.
