Worried that Ovolabs Phlink telephonic software will stop working when you upgrade to Apples OS X Lion? You have good reason to, as it won't work. Anyone who has Ovolabs Phlink will know that support seems to have been dropped many moons ago! No develop is ongoing but Ovolabs is happy to take your money, if you want to throw it at them, in exchange for their product. This is quite sad, as Ovolabs Phlink telephonic software appears to be one of the better packages out there, if you want to use your Mac as an answering machine.
This is where ThinkSoftware.net steps in. Fabien Octave from ThinkSoftware has written a small kextunload startup item that will fix the issue, and allow Phlink to run as it should. I've downloaded and installed the package, it does what it says it does, and nothing more.

PS: I noticed after the most recent update from Apple, that Phlink once again sees calls coming in, but still won't pickup. The unload of com.apple.driver.AppleUSBCDC is still needed.
