HI, I am currently working on a project in mod_managed and i am trying to discover the best way to meet my requirements. i am hoping someone will have some ideas. This could be implemented in one of the other scripting language if needed. What i am trying to do is reprogram a remote device via the phone. The device takes commands in the form of DTMF tones and responds in different DTMF tones depending on success or failure. An example of the flow would be freeswitch -> 342523# device -> 1 freeswitch -> 356789# device ->2 device always responds with one digit and freeswitch sends many. I was hoping to do this with a database and mod_managed but i can't workout how to send the DTMF in mod_managed unless i user audio files for it which seems to be the wrong way to go to me. While i would prefer a mod_managed solution i will take anything i can find. Chris
