The modern era of communication is characterized by technologies like Voice over Internet Protocol (VoIP) and Session Initiation Protocol (SIP). Such terms, though highly popular, are least understood by the people. A lot of people dont actually understand the actual nature and functioning of both VoIP and SIP and the differences between them. The two terminologies are most often confused with each other by a number of people because of the fact that the two are highly related and are mostly talked about in connection with each other. At present, if someone talks about SIP, it is most likely to be interpreted as VoIP. Voice over Internet Protocol or VoIP is basically an alternate service to traditional Public Switched Telephone Network that enables the communication between two VoIP clients by using an Internet Protocol in place of traditional telephony methods. VoIP, thus, is one application that is run on Internet protocol and SIP is one such protocol.

On the other hand, SIP is one protocol that is mostly used for making VoIP calls; however, the two must not be confused with each other. SIP is one internet protocol that supports several applications including VoIP. Though VoIP these days is the most important and key application of Sip, SIP has a number of other applications to support as well. Having supported a major application as VoIP, the popularity of SIP is increasing multifold these days. Other applications that might be supported by SIP include instant messaging and video conferencing. Though VoIP can be run on protocols other than SIP as well, SIP has a plus point that its communication is based on easily comprehensible and humanly readable text. SIP effectively serves to establish a connection between two communication gadgets, either computers or handsets. The popularity of SIP has increased multifold in recent years owing to its unmatched compatibility with the ever spreading VoIP service.

In a nutshell, SIP and VOIP are two independent entities with SIP being a protocol having a number of applications to supports but VoIP is its key application. Similarly, VoIP is one application that can be run on several protocols but SIP is its most compatible protocol. Presently, SIP is vaguely understood as VOIP owing to the increasing popularity of VoIP, however, in future, chances are that SIP applications may dominate the prospect and SIP will be identified separately.
