Skype is not exactly proprietary. The primary supported codecs are
iLBC and ISAC (from GIPS), which are used only for peer-to-peer phone
calls. Well, actually ISAC isn't used too often. When using Skype in
or Skype out, it uses G.729 which is standard but not as efficient as
iLBC.

In my never humble opinion, the problem is not getting Skype to
support standard codec's, but rather why haven't the VoIP instrument
manufactories suppored iLBC, which is license free:

Most of the standard codecs require licenses.
