Pressing the following keys on the telephone keypad affect the speed 

and volume at which the application plays back speech:

1 = increases the gain 

2 = decreases the gain 

3 = increases the speed 

4 = decreases the speed

Bfv API debug mode is turned on. The btcall.cfg file is the user 

configuration file. The wave program is found in the app.src 

directory.

Requires one -p or -r argument.

Using 8-bit 8 kHz and 8-bit 11 kHz Linear recording formats 

for .wav files can produce poor quality with extra noise. If 

recording in Linear format, use 16-bit 8 kHz for .wav files. 

These rates produce better quality recording and are much 

closer to the format used on the phone line.

-c <num>

Call given number, else wait for ring.

-f

Specify record coding format; use the number of 

the format or one of the following names. If
