After you start identifying areas to work on, be willing to experiment a little bit and try new strategies if something isn’t working as planned. Your call quality is essential, so don’t compromise on it. Dig deeper for solutions to problems as they come up.

1. Intro to VoIP

Voice over Internet Protocol (VoIP) is an Internet-based phone service that offers great features and advantages. VoIP has been an option for businesses to use for phone service since around the 1990s. And with faster Internet connection speeds, it’s becoming easier to use VoIP and this type of phone service is becoming even better. Now, the quality is often at least as good and sometimes even better than other types of telephone service.

Having said that, there are factors that can still influence the quality of VoIP calls and cause them to be different from what subscribers might expect. For that reason, it’s important to learn some basic VoIP troubleshooting and to know when it’s necessary to take more active measures to fix a VoIP system.

2. Why Quality Issues Arise

Quality issues can happen for many different reasons. VoIP phone systems have many working parts and are complex, so there are different things that can sometimes go wrong. Being prepared for them can help you boost your system and resolve the issues you’re experiencing.

For instance, some quality problems are related to your Internet connection. Others are caused by weather, distance, or other types of phones and phone services. Sometimes your vendor is responsible, and sometimes there’s something happening inside your building or within your phone system causing interference. These issues may have possible fixes you can implement quickly, although some problems you may have little control over. That’s why it’s important to know what’s happening under the hood of your phone system–so you are empowered to resolve any problems you encounter, as best you can.

3. VoIP Troubleshooting

In this section, we’ll review some VoIP troubleshooting basics so you can quickly figure out if a problem with your call quality is something you can meaningfully resolve, or if you’ll have to get your vendor’s help or get someone else involved.

Poor Sound

This can have a variety of causes, so you’ll need more information. Is the call garbled, delayed, or echoed? Do you hear interference on the line?

  • Distance: Sometimes, great distances can introduce a very faint delay. Combined with other problems, this can add up to the bad sound.
  • Garbled Speech: If your network system isn’t programmed correctly, sometimes the result is VoIP data packets arriving at their destination out-of-order. This may cause the voice conversation to sound unusual and confusing.
  • Delays: Hearing a delay? Sometimes this means your Internet connection doesn’t have the bandwidth to process the call.
  • Bad Quality: Limited bandwidth or bad prioritization settings on your network may be to blame.

Features Not Working

Sometimes, if the other person you’re communicating with lacks a feature, your system will automatically leave that feature out and make it unavailable. It could also be a situation where something is wrong with your VoIP plan, your vendor is encountering difficulties, or your equipment is having issues.

If your service is down altogether, it could mean your vendor’s network is experiencing a period of downtime. If possible, find a vendor with an uptime guarantee (the gold standard in the industry is 99.999% uptime, so look for that if you want minimal quality problems).

Equipment or Network Behaving Strangely

It may be nothing at all–maybe you need to check with your vendor to make sure everything is functional. It’s also possible, though, that you’re experiencing interference from hacking or a security lapse. Or, you need to change the settings.

You may need to experiment a little bit to discover the problem. If possible, get your vendor’s help or have an IT professional look into the situation.

Get the Quality You Deserve

To get the best quality, be sure to:

  1. Choose the right vendor and make sure they provide technical support for your plan and devices if desired.
  2. Be careful when troubleshooting. If you’re afraid to change a setting, call in a pro or ask your vendor for advice.
  3. Make sure you have a go-to person or vendor contact you can get help from whenever something goes wrong and you need to establish service quickly.
  4. Have redundant equipment, service, and Internet connections in place to ensure you always have phone service, even if something happens.
  5. Test your equipment and software regularly.
  6. Do firmware, software, and equipment upgrades and updates on time so you don’t risk unnecessary security issues and malfunctions.
  7. Get the best Internet connection available for your needs and budget.
  8. Configure your network to prioritize VoIP call traffic appropriately, as some older networks are better configured for web browsing and other traffic. If VoIP data is slowed down, you will probably experience worse quality.
  9. Restrict how your Internet connection is used if it is shared between phones and other functions. If you have a lot of users, plan accordingly.
  10. Plan for peak usage times to make sure you have the network capacity and functionality you need to help your phone system be successful.
  11. Teach people at your business how to do some basic troubleshooting and identify people they can go to as resources if they encounter more complex problems with the phone system.
  12. Provide ongoing education and training in using the phone system so everyone is prepared with the help and information they need to make the most of your new VoIP plan.
