Altigen Crashes under SIP DOS attack.


There is a new update released for Altigen’s running 6.5 Update 1. WE HIGHLY RECOMMEND THIS UPDATE. If you have SIP ports open to the public this update is a MUST. We have already been hit on multiple phone systems. It’s very difficult to access the systems remotely as the processor hits 100% and stays there. Please contact us if you have questions.
