"Alternative to Skype" means just that. It doesn't mean "Skype".

No, there are no Skype servers except those that belong to the Skype
company.

Once again, Skype *does not use SIP*. You can have a VOIP service using

compatible in any way. Some phones may be able to talk both, but that's
a different matter.
