[Freeswitch-users] Using mod_spandsp for data exchange

Hi, I was wondering if there is a way to use mod_spandsp for generic data exchange (i.e. file transfer). As I find out mod_spandsp can create soft modems on the system level. If I be able to bridge an inbound call to one of the modems, an external process can use AT commands to establish a connection and exchange data !!! Am I right ? Appreciate all comments, Afshin
