Voice over Internet Protocol (VoIP) is a technology that allows you to make voice / telephone calls using a broadband Internet connection instead of a regular phone line, which has been the method used for the last hundred years. It is a new form of digital telephone service in which calls are sent and received over the Internet. This technology used by most of sip VoIP providers.

VOIP can be used for all kinds of telephone-based communication from text messages, to voice mail, and of course  traditional phone calls.  Because of the bandwidth efficiency and low costs that VoIP technology  can provide, businesses are migrating from traditional copper-wire telephone systems to VoIP systems to reduce their monthly phone costs. Today all new Private Branch Exchange (PBX) lines installed internationally were VoIP. All business phone systems offer cheap calls through this Technology. Thank you for choosing Sip Systems!

SIP is scalable, easy to implement, and requires less setup time than other VoIP protocols. Being text based, it is easy to program. It  is a peer-to-peer protocol, requiring no implementation in the network  level. Users can join in the session no matter what kind of terminal he is using or where he is located. The other person may be logged on to Internet through a PC, or may be traveling with a cell phone. 

Sip provides  advanced, anywhere, anytime multimedia communication.  It is an open standard, allowing multivendor support and integration.  SIP works independently of the type of session, or the media used, giving it flexibility.
