1 – Principle of Astcallback
AstCallBack is a unique solution for mobile phone based on the open-source telephony system of Asterisk.
With AstCallBack, it becomes possible to cut your mobile phone bills. The principle is to use the callback feature of your Asterisk PBX: you choose a person to call, your PBX calls you back then calls your contact and put you together.
This solution is especially advantageous that some numbers are very expensive from your mobile (special number, international) and these calls from abroad (roaming) are sometimes exorbitant.
The “lite” version offers the basic services through a simple and free solution. It is now available on AppStore.
2 – Astcallback settings
- Connect the PBX to the sector and to the computer with a RJ45 cable and switch it on.
- Enter the PBX IP in your web browser (Default : 192.168.1.100 Make sure that you are in the same subnet. For instance :192.168.1.2)

It is YOUR RESPONSIBILITY to secure your configuration so that your Asterisk server can not be used by unauthorized persons. The application AstCallBack Pro will support this security.
