The framework for this SPB is included in the default RA 6300
configuration file. To activate the SPB, remove the comment character
(#) from the beginning of each line that is not a comment, and specify
the called number, so that the SPB resembles the example above. Then
save the file and issue a reset annex session command from na or admin.
The following SPB is defined in Router B's Annex configuration file to
handle Router A's dial-out calls when they arrive at Router B.
