dialer with voice modem

hi, i have a problem, i need to do a dialer form make calls, but the problem is a need to use the microphone but this didn`t work propertly., i`m using vb6 with de ocx mscomm for comunicate with the modem (AT commands), i look for examples o somwhere who can help me but i cann't find there yet.
instead i can make a call ( is very easy), and put this call in voice mode, but a can assign the microphone like voice line.
the secuens of AT command are:
AT
AT&F&D2&C1V1S0=0E0+a8e=1,1
ATS7=60\T0L0M1\N7%C1\Q3*LS1X3
AT+FCLASS=8
AT+VRN=7;+VRA=0;
AT+VTD=10
ATX3DT "phone_number"

i don't know very much about AT command, but i guess this code is ok.
i hope you can help me.....

sorry for the english... it's no very well in me..
