You can install a log watching program that looks out for specific log entries and can take action. Eg; writing a firewall rule to ban the ip address of the system trying to make unauthorised calls. 'swatch' is a good tool for this in linux systems. http://sourceforge.net/projects/swatch/ John On 14/05/13 12:35 AM, Ken Rice wrote:
Re: [Freeswitch-users] Strange CDR entry 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 <-- that's 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...

The call duration is 0 seconds so no they didn't get in. Any accepted call attempt will generate a CDR even if it was not answered.
They're coming in on the 'public' context which'll mean an unauthenticated call on the external profile. That would be the context allowing you to receive calls from strangers. Providing that context doesn't allow them to dial out via providers that charge you this isn't an issue.
