Call blacklisting for the visitor (also referred to as Leg 1) includes:
Temporary Blacklisting: Temporarily prevents the visitor from placing further call sessions for a 24-hour period. Temporary blacklist entries do not currently expire; therefore all numbers that have received a temporary blacklisting are still in the system. If a pre-existing temporary blacklist entry is identified in the system when a secondary temporary blacklist entry is created, the entry becomes permanent.
Permanent Blacklisting: Entry remains until manually edited; changes to a permanent blacklisting must be done manually, with the possibility of whitelisting a visitor to avoid future blacklisting.
All thresholds may be customized. The default and recommended thresholds are as follows:
Single Number used in GUID:
Seven (7) calls in 15 minutes (Directory: 25).
Nine (9) calls in 60 minutes (Directory: 75).
Fifteen (15) calls in 24 hours (Directory: 100).
Multiple Numbers used in GUID**:
Three (3) distinct phone numbers called from the GUID in 60 minutes.
Four (4) distinct phone numbers called from the GUID in 24 hours.
**While people often do this for demo purposes, it is nearly always a result of intentional abuse.
Customer Blacklist recording played:
Receipt of the third call in six (6) hours to the same number.
Receipt of the third call in six (6) hours in the same GUID.
Simultaneous calls per Destination number (Link level threshold) and per Account:
No default: Prevents the destination number or account from receiving call sessions so the set threshold of simultaneous calls per distinct number or account is never exceeded. For example, if set to 2, no more than two calls may be placed to the distinct destination number or account at the same time. Once a session has disconnected, another can connect.
