Zoom Network Monitoring

[jnjuki]

Hi,

We are attempting to set up a reliable way to monitor the zoom service via our Wireless Network sensors (Vendor is Aruba). They can perform VOIP MOS tests to external services.

We are getting half of them reporting ~40% packet loss and the other reporting no packet loss. This is the article for reference: https://help.capenetworks.com/en/articles/3961763-testing-zoom-using-the-custom-test-template-for-vo... 

I wanted to see if this is an approved method of monitoring zoom services (via the multimedia routers) or is there a recommended way to monitor zoom?

Thanks.

maybe zoom phone's new network diagnostics tool will help in identifying network issues.   40% packet loss is very large; zoom phone recommends 2% or loss.

zoom phone network recommendations are:

Network Delay: The delay between the packet being sent and received. Typically, a latency of 150ms or less is recommended. Higher latency values will result in noticeable delays between call participants. For example, call participants might frequently talk over each other because of the delay of audio being sent and received.
Packet: The packets per second (PPS) represents the number of packets that need to be transmitted every second in order to deliver the codec bit rate. Typically a PPS of around 50 is normal.
Frequency: The audio frequency sample rate being sent and received. Typically a sample rate in the range of 16 to 48kHz is acceptable. A higher frequency means better audio quality.
Packet Loss - Avg(Max): The amount of data that fails to reach the final destination. Typically, a packet loss of 2% or less is recommended.

Jitter: The variation in the time between packets arriving, caused by network congestion, timing drift, or route changes. Typically, a jitter of 40ms or less is recommended.
Bandwidth: Displays the current amount of data being transmitted by Zoom. Visit Speedtest to check your current bandwidth. Generally, we recommend 60–100kbps for high-quality voice.
Codec: The audio being used by Zoom Phone. Usually, you'll see Opus, an audio codec that ensures high-quality audio.

Accessing meeting and phone statistics – Zoom Support

any user can assess his/her internet connection from any zoom phone client from any location including home or office.  When enabled by support, users access the tool from Personal>Phone> Network Diagnostics.

'Users can access the network assessment tool to simulate VoIP calls between Zoom and Zoom clients. After you run the network assessment tool, Zoom will give a result of the network assessment score. Contact Zoom support to have this feature enabled for your account.'
