IP telephone systems have to be SIP-compatible. Essentially, this means that they have to be able to handle calls that are sent using Internet protocols rather than conventional telephone protocols. The avaya phones dubai technology is based on a layer of digital information on top of the Internet, which can be transmitted and received as if it were a regular telephone call. This is unlike the conventional telecommunications system, which makes use of copper wiring, telephone lines, or other more traditional communication methods. SIP is not actually a protocol, though. It was developed as a way for computer networks to exchange voice between themselves over a system of networks. When IP telephone systems are used, voice calls are placed over a system which allows them to be converted into data that can then be sent over the Internet. In simple terms, an IP phone system allows users to speak to each other over the same network and to then send each other text messages, video messages, email, and whatever else they might want to do over the Internet. IP telephones work through a standard protocol that is implemented as an application programming interface (API). As stated earlier, an IP telephone system offers voice over Internet protocol rather than just making calls over traditional telephone lines. Basically, when you place a call to another user using an IP telephone system, the other user does not even have to use a telephone line. Instead, he or she simply has to log onto the Internet using his or her Web browser and make the call from there. Of course, since IP telephony systems offer voice as well as data transmission over the Internet, they offer the same benefits as any normal telephone service, such as making long distance calls and making local calls. Voicemail is perhaps one of the major advantages of using an IP telephone systems. With Voicemail, a user can send a message or audio file to another user via the Internet.

Another advantage is that people don't have to be at their computers to place a call, as long as they have Internet access, which is typically free. Another advantage of IP telephones over traditional business telephone systems is that IP telephone systems can support VoIP calling. In other words, users can make use of VoIP services such as Skype and Vonage, which allows them to make voice calls over the Internet instead of using traditional phones that connect via a public switched telephone network. VoIP technology is already commonly used in telecommunication industry. For businesses, using this technology makes perfect sense, as it eliminates the need for traditional business telephone systems.
