We're sorry about the inconvenience. This is actually a known issue. Ooma devices in China have stopped working because China Government restricts our device to work in the country.
But we have done some changes on the Ooma setting that might help us fix it, kindly reboot the device by unplugging its power cable for 5-10 seconds. If still it doesn't work, we're sorry to inform you that your Ooma won't work anymore in China.
Does the Ooma Telo Ooma symbol blick red all of the time, or does it turn blue like late at night or ????
Quote from Ooma: Ooma is engineered for great voice quality but you will need a high-speed Internet connection equivalent to at least a typical DSL connection with 384 kbps upstream and downstream.

If Phonepower Speedtest won't run, try running http://www.speedtest.net/ , then post the upload and download speeds.
You could also go to this site http://ca.ooma.com/help-me and run "Test Your Speed".
If this is the case, the ability to select alternate ports for the VOIP/Ooma VPN connection would circumvent this blocking.
I assume if you're and expat living in China you have a VPN. Is it a VPN service that runs from within your Router? or is it a VPN that runs only on your Mac/PC?
