Hello, I have several Kannel setups in place but this one in particular is causing me some headaches. According to the provider, they attempt to send us a message but the connection gets terminated before an acknowledgement was received. In the provider's logs, we see the message as being sent, in the smsbox.log files, I don't see any "Starting to service..." statements for messages that fail. It seems we're simply not receiving them.
What's strange is the frequency in which this issue manifests. Looking at the logs, I cannot discern any pattern -- it's just randomly working, and then not. I have tried adjusting the timeout to 60 seconds (60000 in the conf), but the issue still persists. This connection is over VPN, but after some investigation, VPN doesn't appear to be causing the issue. Is there a particular set of troubleshooting steps I should follow to determine the root cause? We're using Kannel bearerbox II version 1.4.3 if that's helpful. Thank you.
