TAPI - No dial tone

Asked by: sunnette

URGENT. I am writing a C++ TAPI application which needs to make a outgoing call. I would need to dial 9 to access an outside line. I use lineMakeCall to dial out and feed it 9Wxxxxxxxx where xxxxxxxx is the phone number that i want to dial to. But i keep on getting NO DIAL TONE. Attached is the modem log. Can someone please help.
