Will an OBi 110 work with Basic 768Kbps DSL?

<< < (2/2)

I used to use ADSL with two voip lines and a number of people browsing. Bandwidth was 2.8M down and I think around 700K up. I didn't have any issues with the voip service on the Obi but the Oooma required more bandwidth. I set up Qos with the router to guarantee enough bandwidth for the Ooma and this solved the problem. Qos will guarantee enough bandwidth for the phone at the expense of bandwidth for all other devices.

This.

I really don't recommend using QoS on consumer-grade home routers, as most will just carve out some of your precious and limited upstream bandwidth.  It's best to try to solve the problem by just limiting the use of other things on the network that are sending lots of data, when you are making phone calls.  Of course, upgrading service, if possible, would be the best solution   :-*

Lots of different opinions expressed here.  Which is good.  However, IMO, the VOIP Quality test will tell all you need to know.  And it's not based on anyone individual's subjective experience.

I agree that a VOIP quality test is the first thing to do. If you get a good result with nothing else using bandwidth, then your line is good for VOIP but the result may be misleading. You will need to rerun the test while using bandwidth. (Download a file or YouTube video). If the quality is then poor, then you know you cannot use bandwidth while on the phone.

It is my understanding that QOS does not restrict bandwidth if you are not using the phone. It just guarantees the phone will have whatever the allocated bandwidth is when the phone is in use. If you do use QOS with only 768Kbps, you will see all non-phone internet activity slow when on the phone.
