It shouldn't be the case that for what could be, should be, a single, stand-alone application such as IP-telephony, there is all this cross-linking, central registration, etc., etc., etc., ...
It's probably a consequence of Microsoft buying out Skype and forcing integration with their own universe. So I ask, is there now an alternative to the centralized, you-will-do-everything-our-way system? I've searched, but had no success.
Suggestions?
