The first time it happened was a real eye opener for me ��� happened three times before I figured out exactly how they were doing it, so we changed our processes.
��
Though we had this come from a subscriber the other day ��� was a via a pbx set up by a local telephone technician
��
One thing we are doing now is enabling an international toll bar with pin override on our lines by default so that if any hackers do get in, they cannot call anywhere of interest.
Sort of as a very last line of defence.��
I am a big fan of using IAX instead of SIP where possible so that port forwards are not needed and the client PBX can be behind a NAT firewall.

I hope everyone is having a good break !

If anyone out there has had any of their customers PBX's hacked recently (in the last 2 - 3 weeks) and have experienced a large call flow to say Somalia or some other dodgy destination id be keen to hear from you, I'm after the destination numbers they are dialling.
��
replies off list would be great.
