This is odd since they offer their own VOIP service.
Jitter should be less than 5 ms.
Packet loss should be 0.
Download and upload QOS should be at least 70%.
Maximum TCP delay should be under 100 ms.
Ok I figured it out. I connected the Ooma hub directly to the DSL modem and disconnected all other devices on the network and all voice qualityissues went away. So I thought some device on the network is causing the trouble.raindrop wrote:I am having two issues since last night (3/28/2010).
1) One is the same outgoing calls quality being poor.
2) My DSL is not as fast as you guys, I am running only 1.5Mbps/256Kbps DSL. My Ooma Hub is directly connected to DSL Modem/Router combo and all the other PCs are connected through the Ooma. Usually I do not have any problems with this setup but since yesterday evening my Internet connection became slower than 56k dial-up. When I plugged-in my PC directly in to DSL Modem/Router speed returned to normal. Then for experiment I connected Ooma Hub to DSL Modem and connected PC to Ooma Hub, again Internet connection became slower than dial-up. There is definitely something going on with the Ooma devices.
I think it may be some new firmware loaded into Ooma devices. Can you guys please post your firmware number while reporting the issues?
BTW my firmware version is Rev: 33454.33454
Then I started connecting all the devices one by one and noticed that a bit torrent client on a set top box (Popcorn Hour) is causing the voice quality issues in Ooma hub. The traffic does not need to be heavy, even 40Kbps inbound and 8Kbps outbound is enough to cause breakup in the voice calls. Changing QoS settings in Ooma has no effect on this torrent client. Obviously Ooma's QoS settings are not throttling this bit torrent client. However all other web traffic (i.e you tube videos) has no effect on the call quality since Ooma hub's Qos system takes care of it.
May be something for the Ooma support to look into.
They provide VOIP on their own private network with their own built in QoS (which Ooma doesn't have access to.) That's comparing apples to oranges.joewagner501 wrote:This is odd since they offer their own VOIP service.
How is that comparing apples to oranges?MakoCSH wrote:They provide VOIP on their own private network with their own built in QoS (which Ooma doesn't have access to.) That's comparing apples to oranges.joewagner501 wrote:This is odd since they offer their own VOIP service.
