Weíve already published a page explaining in detail how VoIP works; but in case you donít have time to read it, hereís a quick summary:
Voice over Internet Protocol is a series of technologies that make it possible for you to make online phone calls by converting traditional analog voice calls into digital packets of dataómuch like an email message or an mp3óand sending those voice packets between callers over the internet, rather than over the old-fashioned telephone network.
As for how the VOIP business phone system Doha Qatar themselves function, here is a brief overview of the technologies and processes involved:
In terms of the physical phones themselves, many VOIP business phone system Doha Qatar can be powered by the same Ethernet cable that connects to the phone to transmit data. This technology is called Power over Ethernet (PoE) and is often preferable for businesses because it reduces clutter and can also reduce cost, combining both power and data into a single cable connected to the phone. Other VOIP business phone system Doha Qatar, however, do not offer PoE capability and instead require a separate A/C adapter to power the unit.
In terms of connecting to the Internet, a VoIP phone will be assigned an IP address (just like any computer or another internet-connected device) and then will use a domain name system (DNS) to enable it to connect with other IP phones or VoIP-enabled devices.
As for transmitting voice calls over the Internet, generally speaking, VOIP business phone system Doha Qatar use one of two primary protocols: Session Initiation Protocol (SIP), or H.323. Both of these protocols support not only voice but also other types of dataóincluding video transmissions.
