I'm using Premier service and have two lines setup. If both lines are used at the same time the second call initiated has poor quality. The other party says there are minor drop outs but primarily our voices sound robotic (think poor cell quality). The other caller on the second line sounds fine. Which leads me to think it is an upstream issue. The first call QOS is always fine. I tested it with my wife and can confirm that the quality of the second line is poor.

I have Modeem>>OOMA>>Router configuration. I use a cordless phone and both lines are connected directly into the hub and scout. NOT through our existing house wall jacks. tells me I have 27MBPS down and 2MPS upstream in Denver. I have QOS setup at 1500 kbps up and 5000 kbps down.

Any ideas on what to try to improve the quality of the secons line?

I've used 2 lines at the same time and quality is great on both.
My opinion: put ooma behind the router as you would a pc and control any QOS you may need via the router.
I use it this way with no problems at all.

Thanks for your reply Wayne. I don't have the ability to control QOS on my router (Nextgear WNR854T). I have read that the OOMA HUB is supposed to do the QOS for you under the MODEM>>OOMA>>ROUTER configuration. Cheers

I would suggest to leave Ooma at default QOS. I believe its 384 upload and 0 download. I bet that should fix ur problems. Please post ur experience after this change.

Note: my setup has Qos diabled on Ooma with Qos NOT on in my router and it works excellent.
