Call quality issues over Wi-Fi

Using any VoIP solution over wifi can present issues with call quality.

When you make a VoIP call using a wireless network, the quality of the call can be affected by various factors, including:

Bandwidth: The amount of data that can be transmitted over the Wi-Fi network can affect the quality of the call. If the network is congested or the bandwidth is limited, the call quality may suffer. Review our Bandwidth article for more information.

Latency: Latency refers to the delay between when you speak and when the other person hears you. High latency can cause the conversation to sound choppy or delayed. Review our Latency article for more information.

Jitter: Jitter refers to the variation in the delay of packets sent over the network. High jitter can also cause the conversation to sound choppy or distorted. Review our Jitter article for more information.

Signal strength: Weak Wi-Fi signals can cause various issues with calls. Such as dropouts, distorted/robotic voice and the call to terminate, etc. 

Interference: REIN and SHINE are a type of powerful radio wave that exists in the same frequency range as that used by your broadband service, such as your microwave! Review our REIN and SHINE article for more information.

To get the most out of every call, it's important to have a strong and stable Wi-Fi connection with sufficient bandwidth, low latency and jitter.  

To achieve this please ensure you have QoS policies in place on your router / firewall. Further, ensure you have sufficient Wi-Fi signal coverage and little to no interference from REIN and SHIEN devices. You can measure the signal and interference in your working environment using 3rd party apps and make adjustments where necessary. If supported, also implement WMM (Wireless Multi Media) on your access points to ensure consistency. 

To get the very best out of your CloudCall service, we recommend connecting via network cable.
