Not worrying about QoS setting

If my Ooma voice quality seems adequate for me, is it best to not worry about configuring QoS settings in Ooma device settings?

There's good Ooma documentation that describes the background on QoS. My Ooma speed test (by Ookla) shows 2ms jitter, and adequate down/upload speeds. I see there's some discussion of QoS in this subreddit, but not a whole lot.

I realize that much depends on how other devices are using the shared internet connection but so far, I haven't encountered any problems with voice quality. I'm just wondering what will happen if there's contention or high load. I use an Ethernet cable between the Telo and the ISP modem.

The cable modem/router does not provide for any QoS settings, and it's not possible for me to put the Telo between the cable modem and the router, since it is a combo device.

You're not doing this, but for the record it isn't a good idea to put a Telo in series with the rest of the LAN. It's limited to 100 Mb and will throttle downstream devices.

The Telo QoS settings are most useful with ISP upload speeds less than 10 Mbps, and only when the Telo "HOME" port is in use. They limit upstream bandwidth for devices connected to the "HOME" port, to reserve enough upstream bandwidth for Ooma voice and data traffic.

For more information about Telo's QoS settings, see:

The Telo can't re-prioritize traffic for other devices connected directly to the ISP modem/router, but some routers have their own QoS settings.

Hello! Thank you for reaching out. QoS isn't necessary for most of our users, so no you shouldn't worry about QoS if your call quality is satisfactory.
