E-Soft’s ANI Callback service allows telephone users to initiate long-distance calls by calling a Cisco gateway which, in conjunction with E-Soft ANI Callback, authenticates the user by his/her telephone number (ANI) and connects him/her to the destination party.

How does it work?

• The user calls a Asterisk 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.
• Cisco 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 Cisco gateway can be played to either party.
