It just makes sure that all the bits of the technology are talking the same language.
VoIP and SIP
SIP and VoIP simply govern and set up and transmission of voice calls over the internet. Also, it’s important to remember that while IP systems are designed to make telephone calls over the internet, and therefore they can communicate with other IP systems, they can also communicate with traditional networks, also via the mobile networks and can communicate with all types of different internet device.

How Internet calls are different from traditional cellular calls
Traditionally, telephone calls were made using something called circuit switching this is where a circuit is created when you lift a handset and make communication with a network in which you can hear a dialing tune to tell you that you’re in contact with the public network, that network will then transfer your call to the recipients when the recipient lifts their receiver a circuit is created and the circuit remains open throughout the call. And when the circuit is broken, the call comes to an end.
With IP systems a system called packet switching is in use and this is where your voice is broken down into small packets of data which are transmitted by the internet using much the same system as a music file or email. They may not all go the same way, but they will all end up at the recipients phone and when they get to the recipients phone they will be reassembled back into your voice.

Another thing you’ll need to check is your router, does your route to have the capability, the quality and the power it needs for Internet calling? A lot of good IP systems can be let down by the use of a poor Router. Bad internet connections is a big problem in many countries, but if you’ve stable internet connections with around 512kbps or 1mbps, you’ll be just fine.
How can business save money with VoIP
