callto, skype and tel URL test
This is a simple test of the callto:, skype: and tel: URL schemes. The callto: and skype: URL schemes were introduced by Skype and are usually associated with the Sykpe ecosystem. The tel: URL scheme was introduced in RFC 3699 and is an internet standard. Both are intended to do the same thing, though callto: and skype: more often than not attempt to launch the Skype client.
