How SIP Accounts Work and What Is IP TelephonySIP is a protocol for Internet telephony that 'activates' your VoIP devices and makes it possible to receive and make calls, hold audio and video conferences and chat online. The main difference between conventional and IP telephonies is in that the latter does not use traditional wire circuit to convey the voice. The vocal data is now transmitted in the form of IP packets with the help of software or hardware and software combination. The data are converted into a digital format and compressed by the sender and is decompressed and reconstructed by the opposite side. In simple terms, IP telephony has made a significant qualitative leap in switching from traditional expensive hardware to cost-efficient, easy in maintenance software.
