The latest Ubuntu/Kubuntu V13.10 is released. We download and install it immediately in our lab. It is no problem to run miniSIPServer on these systems. But according to our experience and test result, we dont suggest customers to upgrade systems to V13.10 because it is not stable enough for business deployment now.
So if you are running miniSIPServer on Ubuntu/Kubuntu, it is better to keep your current versions and wait for next LTS version V14.04.
