What is a SIP Phone?


SIP Phone is a modern device that looks like a normal phone, which connects to the Internet and provides convenient and cost effective communications over Internet Protocol SIP.
   At the same time, SIP phone works independently, without requiring a computer, a gateway or router, and allows subscribers to make calls as SIP-telephony subscribers with regular analog phones. SIP phone does not require a dedicated telephone line, as you only need internet for the VoIP equipment to work.
 
   Unlike a regular analog phone, SIP phone supports a variety of business functions (translation, call hold, call forwarding, conference, etc.) and is quite easy to install and configure. For work you can use both wired and wireless SIP-phones.

   SIP phone is intended for personal use and for use in offices. In the latter case, if you have multiple devices, it is possible to organize the office or corporate communications without the use of classical telephony. In this case the location of the phones or the companies does not matter, as it will be as simple as if they are located on adjacent tables. To get started, SIP phone must be connected directly to the Internet, or router.

VoIP Equipment


 VoIP technology (Voice over Internet Protocol) allows you to make and receive calls over the Internet. This makes it possible to significantly reduce the cost of telephony, thanks to the low cost of internet traffic and make free calls within the VoIP network. When using VoIP equipment user connects the phone to a special adapter (VoIP gateway) for accessing the Internet. In the case of initiation of calls from one computer to another user is using a software phone (softphone), which also provides access to the Internet.

User equipment can be divided into three groups:
  • USB phones
  • SIP phones
  • Softphones
Modern fixed SIP phones are the most convenient technological solution, because they can be used for IP telephony, and for work in the public telephone network. They have greater functionality. About SIP Phones and their advantages you can read on our next blog post.
