Pre-Call Announcement service is a technological solution that plays recorded messages for promotional or informational activities of a mobile operator to an originating number (Caller) before outbound routing takes place. Providing information to a caller of any additional charges before proceeding with the call would be one form of pre-call announcement. After the pre-call announcement, the call proceeds as normal to the outbound side (receiver). VoiceGate’s Pre-Call Announcement service allows the administrator to define a set of business rules for every announcement campaign. These campaigns can be altered before the announcement activity starts or in real-time.
