Our outbound trunks include Vitelity for domestic calls and Net2Phone for international.
Twice now, the international system has been hacked with hundreds of dollars worth of calls.
The Vitelity system has not been hacked.
Net2Phone says that the security breach is through my system and not their responsibility. Net2Phone uses weak protection; a 4 numeric character password. I’m not clear whether they are hacking in through my freepbx or guessing the password and going directly through the Net2Phone system.
Any way I can can tell if my system is being penetrated?
