Following our series of articles related to Asterisk, we arrive at IVRs (Interactive Voice Response), which are telephone menus that allow us to choose between different options, press 1 for… 2 for… What we are going to do is configure a context where PSTN calls will enter and from here send them where it suits us, in this case, we are going to play a recording giving three options.
- 1 –> Ext 23
- 2 –> Ext 26
- 3 –> Ext 36
- Default –> Ext 22
If any of the extensions do not respond, a voicemail will be left.
