A Short Guide to VoIP Reliability and Redundancy

Reliability is a major concern for companies thinking about making the switch to VoIP. Luckily, the technology has vastly improved over the last decade as internet connections have become faster and more robust.

Still, there are things you can do to ensure you have the most reliable VoIP service possible. We explore them in this article.

(Skip to the end of this blog post for a short checklist.)

The biggest factor in VoIP reliability is bandwidth

You need to have enough bandwidth to cover all your VoIP (and other networking) needs.

Think of bandwidth like a pipe. It needs to be wide enough to handle your biggest usage peaks and to avoid ‘leaks’. But it shouldn’t be so wide that you’re never using your full capacity. In that case you’ll end up spending more than you need to for a reliable connection.

So, you could just get a bigger pipe. Or (and this is the better option), you could combine several smaller, less expensive pipes to get the job done for a fraction of the price.

This is called bandwidth aggregation. It helps increase the reliability and redundancy of your network by combining multiple connections with different speeds and circuit types into single connection that’s faster and more reliable.

Aggregating your bandwidth this way, rather than going for a bigger pipe, helps protect your network and reduces downtime. It also allows you to prioritize certain services, like VoIP for example. You can give your VoIP system priority so that call quality never suffers when your network experiences a spike in traffic (like when the Olympics are on and everybody in the office is streaming them live). This protects the quality of your VoIP calls.

Uptime is guaranteed by combining multiple connections types. For instance, if you combine broadband with LTE, you can ensure you stay connected even during a power outage.

The VoIP Reliability Checklist

We’ve created a quick checklist to help you maximize the reliability of your VoIP system:

  • Secure a backup power source for your VoIP equipment and your internet router
  • Aggregate your bandwidth using multiple connection types to increase the performance of your system and to build in redundancy if one or more connections fail (this is called ‘bandwidth aggregation’)
  • Reserve enough bandwidth for VoIP to handle any spikes in demand and to prevent other network applications from affecting call quality (your provider can help you figure out exactly how much bandwidth you’ll require for this) – you might want to check out SD-WAN, which is quickly becoming the optimal connectivity solution for multi-location companies
  • If this is your first time using VoIP, consider starting with a phased, risk-free implementation that lets you continue to use your traditional telephones as you transition

And it’s as easy as that.
