Voice over Internet Protocol (VOIP) Explained

By the Experts at Mitel

What is Voice over Internet Protocol?

VoIP is when voice and other data is sent over IP networks, which is the networking of the internet. More importantly, every phone call in the modern LTE network is a VOIP call. When you make a call on an LTE cell phone, that's VOIP. You don't know it's VoIP because it's built into the network. There has been some fine tuning to make that the best that it could possibly be. However, for those people that are naysayers about VOIP, it is now consumer voice for a huge number of customers and they don't even know. When VOIP is done well, it has the benefits that you no longer have a wasteful allocation of resources to fixed capacity channels from point to point. The way that a telephony system works and the way that a packet. The reason that packet data and IP has taken over is because of its efficiencies. When you take huge amounts of traffic and you take all of that traffic through large bandwidth pipes, you can be very, very efficient in the use of those pipes.

 

Why VoIP?

VoIP is can be very cost effective because you're combining it with your data network. In a business, you're taking all of your networking needs and instead of having a voice network and a data network, two separate things, you have a network. You can treat the VOIP traffic with quality of service so that it gets priority and it gets treated better. There are huge benefits because you're buying aggregate capacity and you're able to do away with what is effectively a redundant network. Ultimately, there's still analog around because handsets cost money to replace. There are lots of ... Two cases, man down phones in an industrial plant. If there's regulatory regulations that say you have to be able to call 9-1-1. Let's say you've got a steel mill. You've got phones at various strategic points so if someone gets injured, you can reach for a phone. Those phones almost never get used but they need to be working when they are. So, no one is going to replace those devices. That's one of the challenges that anyone has. You roll out VoIP and you put it on everyone's desk, but you end up with a need to have the ability to support some analog devices as well. It's something that we end up having to do. When you talk about moving to the cloud, that's one of the challenges. VoIP and the cloud fit together perfectly.
