I have developed a TAPI application using voice modem (UNIMODEM TSP). The application is working fine except that when the person on other side (receiver) disconnects the call, TAPI application is unable to prompt the disconnection. After some research, it came in to my knowledge, that is a limitation of UNIMODEM TSP, which does not forwards the message to TAPI. Later, after having a conversation with my modem vendor, he told me that the only way to know when the receiver disconnected the call is to activate the modem's Inactivity Timer. Which will automatically disconnect the call if there is no conversation for a given time. To activate this timer, i have to pass this AT command to my device. AT+VIT=60 The question is, how can i pass this command to modem, when i am using TAPI, or can i open comm connection in parallel to tapi.
