A method for direct voice telephone call using a bluetooth terminal. A direct
voice
telephone call between bluetooth terminals is made using a bluetooth protocol stack
which is constructed so as to make the voice telephone call easy and the voice
telephone call can be made conveniently. Resources can be recycled by using a vocoder
of wireless mobile communication terminal when the voice telephone call is embodied.
The method includes a step of trying to set a call, a step of connecting an asynchronous
connection-less (ACL), a step of connecting a synchronous connection-oriented (SCO)
when the ACL is connected, and a step of performing the voice telephone call when
the SCO is connected.
