Caller ID Security
Caller ID security provides either call screening or call blocking based on a list of numbers entered by the user. Call screening accepts calls from numbers that are on the list while call blocking accepts calls from numbers that are not on the list. If Caller ID security is disabled all calls are accepted.
The Caller ID security list holds up to ten numbers with a maximum length of 13 digits. You can use Ò?Ó as a wild card character. Incoming calls are compared to the numbers in the list, from right to left, and accepted or blocked as applicable. For instance, a stored number of Ò535?8Ó will accept calls from
Note: Call screening and call blocking cannot be enabled simultaneously.
