GSM Callback Function for GSM Gateway

The GSM-Callback function is a feature of the NovaTec-Gateways to realize cost-saving connections from mobile phones to any destination number in fixed or mobile networks.

 

The functionality :

Callback 1

Callback 2

Callback 3

 

 

The advantage:

By using the callback function two connections are charged:

  1. NMG calling user (network internal connection GSM -- GSM)
  2. NMG destination number (via Least Cost Router)

These connections together usually represents a cheaper alternative than the direct dialling of the destination number on the mobile phone, especially for calls to fixed network or international calls.

The GSM-Callback feature can be realised with any NovaTec Gateway.
