Blacklisting—The Si2457/34/15/04 will not dial the
same number more than two times in three minutes.
An attempt to dial a third time within three minutes will
result in a “BLACKLISTED” result code. If the blacklist
memory is full, any dial to a new number will result in a
“BLACKLIST FULL” result code. Numbers are added
to the blacklist only if the modem connection fails. The
%B command will list the numbers on the blacklists.
