Hello everyone,

Is there a way to interface a GSM module so that the controller attached to it externally (8051) can create an IVR menu.

For example, i call a specific mobile number and it starts a menu. e.g
Please press 1 for system status
Press 2 for system shutdown etc etc.

you can make use of voice playback ICs and give o/p directly to MIC In of GSM module. and speaker can be connected to DTMF Decoder. you can easily make such IVR system.

You said:

You mean like the input of the GSM module connected with DTMF ?

Are there going to be any modems involved ?

GSM modules *are* modems.

Most have pins to allow connections to microphones and speakers
so they can act as telephones if wanted.
