This is a device allowing a user to make VoIP calls using session initiation protocol (SIP). SIP is a telecommunication technology developed as a fast, easy standard for delivering IP-based data, voice, and video communications.
In January 2012, the North American division of Panasonic, a market leader in phone systems for small businesses announced a new desktop SIP-phone KX-UT670 and thus expanded its line of SIP UT phone series. This newest offering is the first desktop SIP – phone made by Panasonic, with an open source operating system allowing you to deploy integration solutions for business communications.
