I can’t seem to figure out why the Genesys Cloud outbound predictive dialer fails to connect calls when JMeter 5.6 simulates 50 concurrent sessions in US1.
The API returns a 503 Service Unavailable error immediately after the dialing pattern initiates, while single-thread tests work perfectly.
HTTP/1.1 503 Service Unavailable
Content-Type: application/json
Is there a hard limit on concurrent outbound call attempts for our current tier configuration?
