Are you dealing with a sparse call quality crackle or distorted? This may be a result of “jitter”: a variation or delay in the packets received. This is most common with cloud-based solutions. If you are experiencing the issues with your call quality, here are some steps you can take to alleviate the problem.
A low-frequency hum may be caused by interference from power transformers, power lines, power supplies, or other electrical equipment that are close to a cable or the IP device that the voice path is running on. Radios, microwaves, satellite dishes, wireless routers, cell phones, televisions, or surge protectors may even cause it.
- Firstly ensure there are no loose Ethernet or phone cable can sometimes cause speech to be broken up or distorted. Make sure wires are all firmly plugged into the right ports. Unplug and reconnect each end of the cables if necessary, ensuring the connectors click and lock into place when inserted.
- Try switching to a different cable to see if it makes a difference. Ensure your cables are not excessively long. For example, category 5 (CAT5), they usually look like a twisted pair cable cables should be no longer than 100 meters.
- Make sure your Internet connection and associated routers/switches are powered up and fully functional. An easy way to confirm functionality would be to perform speed/connectivity tests from random PCs on your internal network.
