SIP scanner solution with VOIP.MS

So, finally seemed to find an easy fix for this! Every minute or so, night and day I was getting these ghost calls from a toll free number. When I picked up there was no one there. Found out it was a sip scanner. These calls don't show up in my call records in my voip.ms portal.
If the calls don't show up in your call log how do you know they came from a toll free number?

Then I went into my voip.ms account and went to "Account Settings" - "Account Restrictions" then down the page to "Allow Calls to Countries" and "click to manage list of allowed countries ". Under North America click the + button and choose United States, Toll free and Canada (my choices).
Think about what you've done. You've restricted outbound calls to Canada and the US.
SIP scanners, by their very nature, are inbound calls. Your "easy fix" does nothing to stop SIP scanners.
The "easy fix" to stop SIP scanners is to put the ip address of your VoIP.ms POP server in the X_AccessList field under Service Providers-->ITSP Profile X SIP.
Or if you have a 20x series ATA (which apparently you have) you can also check the X_AcceptSipFromRegistrarOnly field under Voice Services.
You also really should get your OBi out of your DMZ. Having it there leaves it wide open to the world.

A_Friend No, looked from the ObiTalk portal. Will try the Obi direct ip address entry method and check the call history, thanks.
Taoman When the phone rang I looked at the caller ID and it showed the toll free number.
Yes, I thought the same thing, that it only restricts outbound and it doesn't make sense. BUT it did work. That was the only change I made and have made no other changes. I only make one change at a time when troubleshooting.
Prior to this change I did check the X_AcceptSipFromRegistrarOnly field under Voice Services. It didn't help.
Putting it in the DMZ was a suggestion by ObiTalk FAQ when I was having trouble with no ringing prior to this problem.
Thanks for your input, appreciated.

Then the SIP scanners aren't coming in thru your VoIP.ms configuration.
Do you now (or in the past) have any other SP slots configured for a SIP provider?
Really need to look at your call history on your OBi device directly using the local ip address.
redtoy:
Taoman Took Obi out of DMZ. Perhaps that also was part of the problem. All still good :)
Also, call logs do show caller ID of scanner calls. Did have GV as 2nd SP before but not now.

And what SP? slot number are they coming in on? Is that the slot number your VoIP.ms is configured on?
