[Freeswitch-users] Strange CDR entry

[Ken Rice]

Ok look at the 3rd column... This is someone trying to figure out how to get
calls thru your public context with various prefix codexs... Notices how all
the calls end with 972598371070 <-- that¹s the intl destination umber
probably a phone in gaza (definitely in Isreali controlled areas, but I
think I looked up this number or similar number in the past)

To protect yourself, only allow calls to local extentsions from the public
context...
