The new offering, called Skype for SIP, uses Session Initiation Protocol (SIP) to exchange signaling between PBXes (private branch exchanges) and the free or inexpensive voice service.
What protocol does Skype use?
Skype requires that Ports 80 and 443 be open for outgoing Transmission Control Protocol (TCP) transmissions and recommends that all destination ports above 1024 also remain open. In addition, Ports 5060 and 8000 should remain open for incoming and outgoing UDP transmissions. Skype prefers UDP for voice transmissions.
