VoIP Configuration Examples: Dos and Don'ts With VoIP Setups

Do you need a few VoIP configuration examples? Want a few VoIP dos and don'ts? If you're setting up a VoIP connection for your call center, there's a bit of preplanning required beforehand. You want to ensure that you don't configure your VoIP system incorrectly. Because your network will include different types of data, you want to ensure proper setup. This will help you avoid poor performance issues with packets that might take the wrong path. But, we'll get into that shortly.

Here is a little insight into VoIP configurations and a few VoIP configuration examples to help with your setup.

Why VoIP Configurations are Important

To help with your VoIP implementation, troubleshooting your network is important. And, ensuring the right voice over internet provider (VoIP) setup can save you hassles down the line. For example, if your setup isn't correct, it can lead to delays.

With lags in service, this might affect your business because clients will shop elsewhere. Additionally, an incorrect setup can block you from reaching emergency services when you need them.

Do: Confirm Your Bandwidth

With your VoIP implementation setup, you have a certain amount of bandwidth. Maybe it's 50 Mbps or 100 Mbps. That's the internet speed. If you're unsure of your speed, you can contact your internet provider. You can also confirm your speed with an internet speed test.

  • An internet test will confirm your:
  • Upload speeds
  • Download speeds
  • Pings
  • Latency or lags

That's important to understand as you prepare to go through your VoIP system installation setup. You want to ensure it's correct to stop any latency or lags on the endpoints. This will help you to have the fastest connection, speed, and reliability at all times.

Do: Establish Your Power Supply

To help you configure your VoIP setup and to reduce quality assurance issues, the first thing to address is your VoIP phone power. VoIP phones will require power through your Ethernet connection. This is referred to as power over Ethernet or PoE. This differs from a PBX that gives power through its copper wiring.

Now, you can also plug in your phones if you want to use a wall jack. If you take the PoE route, you may want to explore PoE support and ways to manage your Ethernet switch. You may need to upgrade the wires or look at ways to keep your system cool with a fan.

Don't: Avoid NOT Having a Backup

Some people use a fan in a wiring closet. But, you should explore backup support to avoid a power outage. Again, if there's an outage, your VoIP will go out and if it's an emergency you might need to reach emergency services.

Do: Connect to VLANs

One option to explore with your configuration is a virtual LAN. A local area network (LAN) can separate your voice traffic from that of videos and other data on your network. A virtual LAN or VLAN can help you set up the security control your network administrators will need specifically for any voice traffic. And, there are two ways to assign your phones.

You can do this manually. Or, you can use link layer discovery protocols. Cisco has a version for this, too. It's helpful because you're identifying your VoIP phones and using Ethernet switches. You're ensuring the VLAN and IP addresses are properly configured.

Don't: Avoid Manual IPs, but Do Use DHCP

Another point about setting up your VoIP system installation is your IP addresses. Every phone will need to have a separate IP address. You can assign these based on Dynamic Host Configuration Protocols (DHCP). This ensures the phones are on the network and using their own IP.

Dynamic host configuration protocol is a client-server protocol that manages IP addresses. That means you don't have to do the setups manually one at a time. Just send your request to DHCP once you're ready to connect your phone lines.

Do: Configure Your VoIP Softphones

Because more businesses are using softphone software, you need to prioritize your voice traffic. Any wireless LAN access points should have sufficient coverage. This can help you avoid traffic congestion or any dead spots. Again, you want to reduce lags and latency in calls.

Do: Use the Highest-Quality Headset and Set Up Your VLAN to Recognize a Voice Packet

Headsets are important because you want the highest quality on calls. Additionally, you need to view your softphone performance. This can help if there are any sound-related issues. A softphone can sometimes cause you to not be able to separate your voice traffic from other traffic. But, this is imperative. Why? You need to be able to find any voice packets so they can be prioritized. Even when encryption is used, you need to be able to get your voice traffic through so there are no lags or latency with calls.
