6.2.3. Blacklisting
Blacklisting prevents dialing the same phone number more than three times in three minutes. Any attempt to dial a
fourth time within three minutes results in a BLACKLISTED result code. If the blacklisting memory is full, any dial to
a new number results in a BLACKLIST FULL result code. The number of allowable calls may be adjusted in S43. If
S43 = 3, the third call in S44 seconds is blacklisted. The blacklisting time may be adjusted with register S44
(second units). A number is added to the blacklist only if the connection fails. The S42 register controls blacklisting.
Any number that is currently blacklisted is reported with the %B command.
