Spam Guard is an automated feature that blocks known and suspected spam calls while allowing legitimate calls to ring through to your business. It utilizes scoring thresholds set in the CAI app and evaluates scores reported by TrueCNAM.
How Spam Guard Works
- The default threshold for most customers is Level 3, which blocks calls with a TrueCNAM score of 80 or above.
- Spam calls with lower scores (considered low or medium risk by TrueCNAM) may still get through.
- Lowering the threshold increases the likelihood of blocking spam but also increases the risk of inadvertently blocking legitimate calls.
Scoring Thresholds
Spam Guard scoring thresholds are defined as follows:
| Level | Score Range | Description |
| Level 4 | 90 ≤ score ≤ 100 | Blocks calls with the highest spam probability. |
| Level 3 | 80 ≤ score < 90 | Default for most customers, balancing spam prevention and call legitimacy. |
| Level 2 | 40 ≤ score < 80 | Blocks calls considered medium risk. |
| Level 1 | 0 ≤ score < 40 | Allows nearly all calls to ring through. |
Note: The threshold level can be adjusted on the backend by support to meet your business needs.
