SIP VoIP Gateway
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.
Numbers starting with 0800, 800, 1-800 are usually toll-free for the caller; the called party, however, has to cover the charges on those calls.
