I am having a small VB application to call customers through my laptop. I use tapiRequestMake Call 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....
