This product mostly works, but on some machines, no matter what I do it cannot dial out. The developer says to reset the audio preferences (change them and change them back again) and promised an update over a year ago, but this has not been fixed to date.

2 machines I have it works fine, 3 other machines it cannot dial (crashes). That said it works better for me than loudhush ever did (and this is free where loudhush is not).
