I am using a Dialogic modem card with CVI. It is a modem/telephonics card to make and receive calls. A complete DTMF read/send section is available. Not cheap, but very powerful. It comes with a DLL that can be accessed via CVI (create DLL import library, etc.).

Hi Jon,
I wrote the code in LabVIEW, but since it's all DAQmx calls, all you need to do is copy over the code VI by VI into its text-based equivalent (DAQmx is the same function set regardless of programming environment). The text-based DAQmx code Reference help is available on your computer Programs>National Instruments>NI-DAQ>Text-Based Code Support.
