After you run the test, click on the Advanced tab, then in the lower right corner there is a link that says "View text". Click that and then you can copy the results by highlighting them and the Ctrl-C or right click and click copy.

Thanks for the tip!

Following is my test result using TWC and modem-ooma-router connection. My experience with Ooma VoIP quality is not as good as mobile phone. I can hear other side fine but other side voice quality is not as clear as from mobile phone. Checking "Download quality of service" is only 34%, maybe due to 134 ms max TCP delay. Is there anything I can do on my side to improve the delay before calling cable company? Thanks again.

How do you have the Ooma hub connected - to your cable modem or to a router?

Have you adjusted QOS settings on the Ooma hub?

Be sure to turn off any anti malware before running these tests. I have confirmed that Kaspersky affects the results significantly.

Cheers,

My Ooma hub is connected directly to cable modem. As far as QOS settings on the Ooma hub concerns I'm using the default settings which is 130kbps for the call. I don't have a 2nd line, neither a fax machine at home. So I think this setting is good enough. However I seem to have the same issue as everyone else on the previous long thread discussion.

If the other party can't hear you well, that's upload. Try changing your Upload QOS to 800 Kbps.
