I am having a small VB application to call customers through my laptop. I use tapiRequestMakeCall for this to make calls using a modem. I have to problems where I need help from someone expert on TAPI.
1) My phone line is connected to PBX and hence I have to dial 0 to get the outside line. So how do I pass a number with 0 to get an outside line. Just 0 followed by phone number does not work. If I use 0,7145155315 in dialer.exe it works. But when I send 0,7145155315 using tapiRequestMakeCall it tries to make an internet call and hence it fails. How do I force it to make a phone call instead of internet call.
2) When I dial directly through dialer.exe it connects the outside and I am able to hear the other party speak. But they cannot hear my voice. i.e. the voice transmission is one way. Can anyone explain what could be the problem and how do I make it 2-way. I have an internal built-in modem on my laptop and I am using a Headphone with mic to talk. There is no problem with my headphone as it works good with skype and other net talking applications.
Please help. This is urgent.
