VoIP

VoIP (voice over IP) is a term that is used to transmit voice over the Internet. It makes phone calls by using an internet connection instead of using analog telephone lines.

Kbps

Kbps stands for kilobits per second it is used to indicate the data transfer speed and measured in units of bits per second (bps).1 kbps = 1000 bits per second (bps).

Bandwidth

Bandwidth can be defined as the amount of data transmitted in a fixed amount of time it expresses in bits per second (bps). The number of VoIP channel depends on your bandwidth. If you needed 100 VoIP channels your bandwidth should be high which can support these channels.

SIP

SIP stand for session initiation protocol is used for voice-over IP (VoIP) calls. It is also called IP telephony signaling protocol and it can also be used for instant messaging.
