How to Block Incoming Calls 

MSI Caller ID software products have the ability to block calls from selected telephone numbers. Calls can be blocked by marking specific telephone numbers for blocking, or by entering a range of telephone numbers to block.

To block calls from a specific caller, do the following:

1. Go to the PhoneBook
2. Select the show all numbers option
3. Select the telephone number to be blocked
4. Double click this number, which brings up the DB Details display for this number (see below for an example of this display)
5. Select the Options tab
6. In the Incoming call options area, select the Reject Incoming Calls selection
7. Press the Update button

Then all calls from this caller will be blocked.

CallAudit Voice Users: When using CallAudit Voice, callers marked as blocked will have the Call Blocking Message played to them before the software rejects their call.

To block calls from a range of telephone numbers, do the following:

1. Go to System Preferences
2. Go to the Calls tab
3. Press the Call Blocking Options button
4. Follow the onscreen instructions for call blocking. 
5. See the Help file for further information

 

BACKGROUND INFORMATION

Incoming calls come in different categories:

1. Calls where the actual telephone number is provided
2. Calls from Out Of Area callers
3. Calls from Private callers
4. Calls where no Caller ID information is provided

The first case is where the actual telephone number is provided by Caller ID (and perhaps the name as well if your telephone company provides name service as well). This is viewed as the normal case.

The second case is where the caller is out of the calling area supported by your local telephone company. In this case rather than the original true telephone number, only an O is provided as the Caller ID number. This indicates that the call is from an Out of Area caller.

The third case is where the caller has blocked their number. . In this case rather than the original true telephone number, only a P is provided as the Caller ID number. This indicates that the call is from an Private caller.

The last case is where no Caller ID information at all is provided by the telephone company. This occurs for calls where the originating telephone company has no ability to transmit any Caller ID data at all. This is usually due to a telephone company, mostly in rural areas, with out of date equipment.
