Mark All of SIP trunk customer have to Registers on the network. It?s a requirement we adopted some time ago. I also just checked and Bursting is disabled on my latest account that had the issue. The had 5 SIP trunks but were averaging 20 CC ILD calls. So we may have encountered a Broadsoft bug. I am working on trying to come up with a plan for testing?

The SBC in your core will only allow SIP Invites from the registered device. If you have non-registered SIP Trunks in Broadworks this is very dangerous.

If so please share what you have done / or will to make it stop We have a series of smaller SIP trunk customers using Broadsoft trunk groups. By design the trunk groups have a concurrent call limitation based off the customer?s order. These smaller SIP trunks groups when compromised are able to run up HUGE fraud bills even tho they only have 5 or 6 SIP trunks. Needing to know if anyone else is seeing this that has Broadsoft and what was done to protect yourselves?
