The term SIP phonedescribes a piece of hardware and software, which enables a user to (originate) and/or modify and/or terminate ulti!edia sessions by using the SIP signaprotocol"

#ou may rightfully as$ now about the use of the term %SIP phone& in the conte't of ISthan using the term %IS phone& to describe the IS endpoint)

The answer is *uite simple+ e do want to emphasi-e here that IS phone is really nothSIP phone with cellular capabilities and some e'tended SIP functionality (defined by the standard)"

It should go without saying that SIP phone is also capable (in addition to its SIP signalingcapability) of e'changing media with other SIP phones or gateways (using common code. or 01C o2er TP), otherwise it would ha2e been pretty useless (or limited to 3ust SIP signaling in the lab""")
