About 3 months ago I set up my phone switch Asterisk 14 (FreePBX distro). I configured OpenCNAM and deposited about $20 in my account there. Things worked well for about a month - and then I noticed inbound calls were “unknown caller” - so I logged onto OpenCNAM and my account was ZERO - crazy since we receive 20 calls a day max… so I contacted their support and they sent me a log showing that they had received over 4200 CID queries for the same phone number from my switch - all in just a few minutes - often multiple times per second second - all queries do show they came from MY IP – it ran my account out of funds…
I don’t know what to do or how to proceed because I don’t think I dare to put more $$ on my opencnam account - probably get the same results eventually…(!)
I’m attaching a portion of the logs from OpenCNAM (I truncated my IP address to the first two Octects)
Is this some type of attack on my server? or a bug?
