I have a small interactive system setup with IVM and 2-line Synway USB telephony board running on Windows XP SP2. A person calls in then goes through the prompts then some data is written to the database and that's it (Immediate hangup in the last prompt).
Here's the problem... After the last prompt the program seems to hold the line for a while and then although it shows that it released the line it does not. When I call the second time the line is busy. I have to physically unplug the usb cable from the modem to release the line and then restart IVM to pickup the hardware again.
Please let me know how to resolve this. I need to fix this asap. Thanks.
