I’m using the Desktop Toolkit ActiveX version 7.1 in my program, and I’m trying to send digits while I’ve got an active call. I can use the TSendDTMF method for the Line control to send digits for some numbers that I call, but we’ve got other numbers at our company which, when dialed, go directly to a menu without ringing.
After the menu recording is finished, I’m prompted to press “1” or “2” on the phone. The TSendDTMF method gets fired successfully, but no digit is sent. If I call other “non-menu” numbers which require the caller to press one or more numbers on the phone, then the TSendDTMF method works fine.
Are there other methods to use besides TSendDTMF which may work for sending digits to these “menu” phone numbers?
