incoming voice call, it should release one B channel for the voice call.
You need to subscribe the call waiting service for the Call Bumping feature
(Bandwidth release for incoming voice call) to work.

Q: My Internet Charging is excessive that I have dialed.

Make sure the MLP(128KBps) call can be accepted by your ISP before you
activate the MLP mode. TA will try to establish the second B channel in MLP
call while necessary.
If your ISP doesn't allow the second B channel, the phone company
will bill you for attempting multiple connection.
Q: I do not have a satisfactory data rate transfer for my 64kbps/128kbps
connection.
Check if your RS232 COM port speed is set to 115200bps or above.
