In another example, the scoring agent 110 may generate a trust score based in part on a pattern of historical voice connections to high risk or high cost destination endpoints associated with a customer account. The pattern of historical voice connections (or call pattern 128) may indicate customer behavior for calling high risk or high cost destination endpoints, and the pattern can be used in a decision whether to allow a connection request to a high risk or high cost destination endpoint. For example, in the event that a connection request to a high risk or high cost destination endpoint corresponds to a pattern of voice connections to the high risk or high cost destination endpoint, or similar high risk or high cost destination endpoints, then the scoring agent 110 may generate a trust score that allows the connection request. However, if the connection request deviates from the pattern of voice connections, the scoring agent 110 may generate a trust score that denies the connection request.
