Both play files should be of approximately the same duration (±0.25s).
To find the proper index of an interface, open OptiCall™ in the GUI mode,
and click on the drop down list box as if to change the terminating or the
originating interface. Find that all entries in the list box start with a number.
This number is the index of the line. In the future, a command line tool that
may be used to query the index for a certain interface may be provided.
If either the terminating or the originating side is an audio interface and not
a telephony device, the timing printed to stdout as a result of the call is
meaningless. It is only provided in order to maintain compatibility between
scripts.
Example (should be written on one line):
Make a loop call from line 0 to Line 1, dial 01234, use the default reference
file and store the results in C:\\temp, as Test-line0 (degraded file) and Test-
line1 (echo signal).

The bitmask defines
which interface is
sending (playing) the
file. Bit 0 is the
originating interface
and bit 1 is the
terminating
interface. Enter 3
for both interfaces.
