Frequently Asked Questions


What is SIP?

(taken from Wikipedia)


The Session Initiation Protocol (SIP) is a signaling protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP). Other feasible application examples include video conferencing, streaming multimedia distribution, instant messaging, presence information and online games. The protocol can be used for creating, modifying and terminating two-party (unicast) or multiparty (multicast) sessions consisting of one or several media streams. The modification can involve changing addresses or ports, inviting more participants, adding or deleting media streams, etc.

The SIP protocol is a TCP/IP-based Application Layer protocol. SIP is designed to be independent of the underlying transport layer; it can run on Transmission Control Protocol (TCP), User Datagram Protocol (UDP), or Stream Control Transmission Protocol (SCTP). It is a text-based protocol, incorporating many elements of the Hypertext Transfer Protocol (HTTP) and the Simple Mail Transfer Protocol (SMTP), allowing for direct inspection by administrators.



What is Broadband?


Broadband Internet is the future of telecommunications and data communication tools. It is a network that is capable of much more traffic at higher speeds than the traditional telephone copper cable.

Both individuals and businesses can utilize the higher data flow volume more effectively to communicate with all parts of the world via the Internet, for example, send their own television broadcasts from a video camera or listen to radio from anywhere in the world.

Today's internet, e-mail and World Wide Web (www), has two different visions.

  • One vision is to use the Internet as a platform where anyone is able to produce and share information.
  • The second vision is more commercial; a place for us to consume services such as games, TV on demand and e-shopping.

Bandwidth is a term that describes the capacity of this network, it is measured in how many bits are to send per second. Broadband is often referred to as data communication with 2Mbit/sec. While a typical modem communicates with the 56 000 bits per second (56Kbit/sec.) “A huge difference.”

Broadband is available in several different forms:

  • Broadband via telephone
  • xDSL
  • ADSL
  • Broadband via cable, fiber or wireless solutions.

With broadband, you can be constantly connected to the internet and for this you pay a flat fee.
