Firms warned on 'phreaking'.
It says because many businesses have an in-house phone network that uses computer and digital technology, tech-savvy fraudsters are tapping into vulnerable networks and using them to make calls.
Known as "phreaking", this type of fraud has been around for years with hackers often selling access to networks to organised gangs.
Cowens director Stuart Williams said: "Phreaking is costing businesses hundreds of thousands of pounds every year.
"Unless victims are always checking bills and telecoms reports and reviews, it's a crime that can go on undetected. We've seen a rise in businesses that have either been phreaked or know of victims."
