call Call quality is influenced by several factors, including device software and hardware and the network a device is connected to. Here we explore the key factors that influence call quality and recommendations for improving call quality.

Agent login from office using web call or softphone then it should have 150 kb/Second dedicated for the agent and there should be having proper network bandwidth using Broadbank dedicated or 4G/LTE enabled internet connection on mobile internet. And the signal strength can be checked using apps like “network “network cell info lite“ lite“ which will give you the network strength.

The network the device runs on has a big influence on call quality thanks to factors such as jitter and latency.

Jitter and Latency

VoIP Web calls involve the transmission of a continuous train of voice data packets. If the network is congested, some of the first packets sent may reach a recipient later than other packets. This out-of-order receipt of packets, known as jitter, can result in the audio sounding jumbled or robotic. Jitter is measured in milliseconds of delay, and jitter values higher than 30 milliseconds on web calls can lead to poor audio quality. High network congestion can also lead to packet loss, resulting in chunks of audio never reaching the intended recipient.

To minimize network and device issues and improve call quality, Plivo Phonon recommends:

• Using a high-bandwidth fiber connection from a reputed internet provider. Dedicated business internet connections generally come with guaranteed SLAs on bandwidth and latency.

• Use a physical Ethernet connection instead of Wi-Fi when possible.

• If using Wi-Fi, limit the number of devices connected on the same channel.

• Using high-quality Wi-Fi routers built for enterprises or real-time gaming. Look for routers that come with advanced QoS features.

• Auditing your network firewall and NAT settings to check for transmission delays due to improper configuration.

• Avoid large data transfers on the Wi-Fi network during calls.

• Limiting bandwidth per connected device to ensure an even allocation of total available bandwidth.

• Avoid calls over cellular data connections (4G and older) as they are not optimized for low-latency traffic during the login.

• During the work from home, the agent should have a broadband connection which should have proper bandwidth dedicated or Mobile data which less than 4G/LTE

• Ensuring uplink and downlink bandwidth availability of at least 50Kbps 150Kbps for voice transmission.If operating in a low-bandwidth environment, capping the bandwidth to be consumed on the call using the maxAverageBitrate configuration parameter of the Browser SDK.
