Detect dial tone via a modem


Recommended Posts

I am looking for a command line or vbs script to initialize a telephone line and detect if there is dialtone. I am having issues with my voip provider and need some data to harass them.

Anyone have any ideas?

just an idea:

every modem you find nowadays should have dial tone detection. You could send AT-Commands over the COM port to let it open the line and detect dialtone. If it doesnt get a dial tone in a certain time frame, you should either get or be able to pull some return value from the modem.

You need to find the manual for your specific modem, there should be a listing of AT-Commands in it.
