Main and called dynamic blacklist

“Business Management”—–“Softswitch Management”—–“System Parameters”, you can view the settings of related parameters

Application scenario example:

Suppose you want to realize that the called number reaches 6 times within ten minutes, and the system judges the number as a malicious call number to prohibit the call. How to achieve this?

“Business Management”—–“Softswitch Management”—–“System Parameters”, find the parameters

Set as follows:

SS_BLACK_LIST_MALICIOUS_CALL_CHECK_INTERVAL (Malicious Call Dynamic Blacklist Called Number Monitoring Period (seconds) 60-86400) is set to 600 seconds

SS_BLACK_LIST_MALICIOUS_CALL_LIMIT (Malicious Call Dynamic Blacklist Called Number Calls Maximum Number 1-1000) is set to 6 times

Then, when the called number is dialed 6 times in 10 minutes, the system will automatically add the number to the dynamic blacklist, which can be used in “Number Management” ——- “Dynamic Blacklist” Query the forbidden number.

SS_BLACK_LIST_MALICIOUS_CALL_EXPIRE (The malicious call blacklist called number expiration time (seconds) 60-2592000) The default setting is 3600s, which means that after the last call of the number is added to the dynamic blacklist, after 3600 seconds, the system will automatically release the number.

The setting principle of the dynamic blacklist of the calling party is the same as the setting principle of the dynamic blacklist of the called party, and is not described here.

In the “Number Management” ——- “Dynamic Blacklist”, check the dynamic blacklist number.
