• Pre-Defined DID/DDI Trigger Call-Back
  Users call a pre-allocated corporate telephone number, often called a DDI (direct dial in) or DID (direct inward dial) number, and then receive a callback call on their registered callback number. Once receiving the callback call, users can make unlimited consecutive outbound calls by keying double pound key (#, #).

Users dial the/a DDI number to trigger the callback to the registered user, and can then make unlimited consecutive outbound calls by keying double pound key (#, #).
• SMS Call-Back
  Users can also initiate a Callback by sending an SMS message to the designated number which includes the destination number. After receiving the callback call, users can make unlimited consecutive outbound calls by keying double pound key (#, #).
