Can you check your phones call log to see if a connection was made but not completed, should see the SMS centre number in the phone log if it connected.
Did the visitors have there own code, if yes check report Open/close is on for that user in Wintex.
Hello:
I have virgin media and rather annoyingly I cannot seem to get a breakdown of calls which cost <50 pence. Apparently they don't provide it on my online billing or statement.
Visitors each are setup as different users with their own codes.
I actually didn't use Wintex at all and actually not sure how to! but interestingly I did just test the users and both made SMS notifications today, so I am ruling out that the users aren't configured properly.
You raise an interesting point, just maybe the dialer had a fault that day, the phone line was down, the sms gateway/center was engaged and/or the gateway didn't relay for whatever reason.
I'm going to do another test by setting the system to alert me of all events and see if I can repeat the fault.
Thanks
