Hi everybody, I found the following problem today: We are sending hearbeats to our SMS-C, usually there aren't any problems.
But today I receive "Alert (operation 31) was not ACKed within 120 seconds" and in parallel: "hearbeat with load value 0 received" 120 seconds is our configured timeout. When the heartbeat is received, why the alert happen?. Or does operation 31 have a different meaning? Or is the message due to hearbeat-requests sent from the sms-c and not the answer to our request? Our GSM provider can see our heartbeats in their logs and send an answer. Thanks!
