Rahul,
You may want to try phoneSetHookSwitch(hPhone, PHONEHOOKSWITCHDEV_SPEAKER,
PHONEHOOKSWITCHMODE_MICSPEAKER).

The API sequence needed for this looks like:
lineInitializeEx()
lineOpen()
lineGetID("tapi/phone")
phoneInitialize()
phoneOpen()
lineMakeCall()
phoneSetHookSwitch()

Try it with TAPI Browser TB20 before starting to code anything yourself.
See my TAPI and TSPI FAQ:
