VoIP – IT ALL COMES DOWN TO THE NETWORK

Author: This week’s blog post was written by Diana Small, TeraGo’s Voice Solutions Product Manager and vertical expert.

For as long as I’ve been in the role of Product Manager, I’ve been asked by our Marketing team time after time, what differentiates our SIP, hosted PBX and UCaaS solutions from other solutions in the market? My answer is always the same: the network. It’s true that we’re well priced competitively, deliver high quality support, and our feature set is rich, but that’s not the biggest differentiator. Our biggest ‘WOW’ is our network. The response I usually get is: “network is not sexy”.

I decided that I needed to dispel this myth: our network is sexy!

TeraGo’s Network is sexy because of its sophisticated design that uniquely supports voice for businesses, specifically prioritizing Voice through our WAN network. Not to mention that it is wholly owned and national and promises %99.999 core availability

When you want the cost savings and all the other benefits of having a VoIP solution, you are tied at the hip with your provider; so if your network quality is poor, your VoIP service will be poor. Whether we’re talking about basic SIP (phone lines, usually with your own PBX), hosted PBX, or a full blown Unified Communications as a Service solution, the reliance on your network provider is the same.

Voice is not email
Consider your voice service; it is a mission-critical Network application. Your company’s most critical application may be email, as it is for many companies, yet email typically demands little of a Network because it is forgiving of network delays. Email was designed to be queued and slowly travel the Internet. When your network has slowdowns, email doesn’t mind. Nonetheless, voice is a real-time application and it does mind.

Your SIP-based solution uses VoIP technology. VoIP traffic must not be competing with someone downloading the latest app or streaming audio from the Internet. VoIP is more delay-sensitive than 99% of other applications that typically run on your network. Little known fact: audio is more sensitive to delay than video! So how do you make sure VoIP gets the prioritization it needs?

You will likely implement Quality of Service (QoS) on your Network or reserve a specific portion of Network bandwidth exclusively for high priority traffic. Quality of Service (QoS) policies are used to mark specific types of traffic for high priority delivery by the Network. 

The right kind of network
The TeraGo network is uniquely designed to support voice for businesses. For a company to run voice services, you will need to ensure that your SIP provider prioritizes Voice through their WAN network. That’s where most providers fall flat.

There are two ways of doing this:

  1. Most VoIP providers run the service through VoIP over the Internet (Over the Top), where you would use the public Internet as a transport for voice.Using the public internet means that you will be affected by congestion on the Internet. Even running a VPN over an Internet connection is not recommended for deployments that require a high service level since VPN can be affected by congestion on the Internet. The internet is like the Wild Wild West; you’re always running a risk.
  1. TeraGo Voice services run through Private Transport. You can use a private transport connection directly to your Hosted PBX/UCC provider.TeraGo’s network runs your voice service above and beyond your internet. There is no competition. Our network is national, private and is designed precisely for businesses. We prioritize TeraGo voice within our own private network so that Voice receives precedence over non-real-time traffic.

Is one better than the other? Absolutely. When you choose a service that runs through a private transport like TeraGo’s, there are fewer dropped packets, less latency, and less jitter. With TeraGo, you’re guaranteed that even at the busiest times, you won’t be missing any calls.

Typical VOIP solutions are over the top and often get bad press for quality and experience …VoIP uses a particular set of Network protocols some for setting up calls, such as SIP and others for the actual call session, such as Real-time Transport Protocol (RTP). VoIP success can be stymied if any of those protocols are not properly transmitted between call initiator, call server, and ultimately call receiver. During a call, VoIP call quality can suffer from three issues related to the Network – Packet Loss, High Latency, or High Jitter (packet delivery disorder).  All three of those conditions can arise for a number of reasons, but most commonly result from simple Network congestion.

So, start by listing all of your Hosted or web-based applications, such as: hosted e-mail, CRM, Salesforce, Google Docs, Office 360, and don’t forget all the people who will be streaming soccer or baseball games during the day. All of those will all affect your voice experience. Now ask yourself, do I need a sexy network?
