The largest invoice that I personally reviewed as a consequence of Call Hacking was over $500,000.  Yes, you read that correctly- a half a million dollars in fraudulent international calls consumed in just ONE bill cycle. This company had landline (analog) phone lines and a traditional phone system.  Before we talk about how SIP trunks offer better security against Call Hacking, let’s define SIP Trunks and Call Hacking.

What are SIP Trunks?

Session Initiation Protocol (SIP) is a business-class form of Voice over IP (VoIP) phone service.  SIP Trunks are virtual phone lines that are widely used in conjunction with IP phone systems.  SIP Trunks are more cost effective than traditional landline service and include an automatic disaster recovery feature.  

What is Call Hacking?

Call Hacking (also known as PBX Hacking) is a rising threat in the telecommunications industry.  Call Hacking usually involves a third party making international calls at the expense of a business.  In most situations, hackers are calling through traditional phone lines by gaining access to the company’s voice mailbox. 

How does SIP Trunking Offer Better Security than Landline Service?

Unlike large Carriers that supply traditional landline service, SIP phone service offers real-time monitoring of international calls.  For example, if 15 international calls are made within 15 minutes, your company is alerted to verify the legitimacy of the calls.  If 30 international calls are made within 30 minutes, then international calling ability is disabled until usage verification is confirmed.  

Additionally, SIP phone service and cloud phone systems offer custom settings such as requiring a PIN code to place an international call, restricting international calling on certain hours and days, or disabling international calling completely.
