“Error: invalid_dialer_configuration. The predictive campaign update failed due to strict validation rules in the Outbound platform.”
Encountering this 400 error when attempting to modify dialer settings via the API. The payload aligns with documentation, yet the platform rejects the configuration for our predictive campaign. Is there a specific constraint in the current Genesys Cloud release regarding concurrent call limits or compliance settings that triggers this? The dashboard shows no active alerts.
The official documentation states that predictive dialer configurations are tightly coupled with the underlying trunk capacity and regional compliance rules, especially when BYOC trunks are involved. In our setup across 15 APAC trunks, we frequently encounter validation failures when the max_concurrent_calls exceeds the registered SIP endpoint limits or when compliance_wait_time conflicts with local telephony regulations. The error often stems from a mismatch between the requested dial rate and the actual trunk throughput capability. Check if your outbound_number_pools are correctly mapped to trunks that support predictive dialing. Some carriers restrict high-frequency outbound traffic, causing the platform to reject the configuration preemptively. Verify the dialer_settings object in your payload. Ensure preview_mode is disabled if you are forcing predictive mode, and confirm that wrap_up_time aligns with your agent queue settings. A common fix is to temporarily reduce the dialer_capacity to 10% of the trunk limit to bypass the strict validation, then incrementally increase it while monitoring SIP registration stability.
