It is corresponding to SIP traffic according to my Asterisk logs.
But my xport portal is showing no phone calls being made.
Is there a way I can block SIP traffic except between WXC and my office?
I am running fail2ban on the asterisk box. And between the asterisk box and internet is just an ADSL modem.
Is there anything else I can do to stop incurring all this traffic and charges arising there from?
I did call tech support and they said they can't do anything about this, they can't even confirm that it is SIP traffic. The guy said he though it was unlikely since it was mainly uploading but all I have is just the Asterisk box, and a truenet probe installed.
