Ani Callback - Automatic Number Identification.
Vocalynx ANI Callback service allows telephone users to initiate long-distance calls by calling a gateway which, in conjunction with Vocalynx ANI Callback, authenticates the user by his/her telephone number (ANI) and connects him/her to the destination party.
  • The user calls a gateway (local or international phone number) and hangs up. The script disconnects the call without picking up the phone, so that the user is not charged for the call.
  • The user is authenticated by his/her phone number.
  • Gateway calls back, giving the user a dial tone, retrieving the dialed number and establishing a VoIP call with the destination party via a third-party VoIP gateway.
  • Optionally, voice prompts generated by an IVR running on the gateway can be played to either party.
