How much bandwidth does OOMA use?

Dr. J 25,036 3,353 December 3, 2010 at 08:15 AM
I'm near trigger ready on a ooma hub for my house but I also rely heavily on internet-based technology like netflix / other streaming stuff.

If I get an ooma call, will that degrade other services significantly?

64Kbps max. for upload/download. The bandwidth is not the only factor that could affect VOIP quality. Transmission latency and the number of overall network packages could also hit different bottlenecks.

really should now more likely the other service will degrade OOMA if you can't prioritize? An ISDN digital line uses 64k for a phone line so you are not talking much bandwidth but the packets all need to arrive in the correct order. No way to buffer a phone call like you can Netflix!

well it depends how much voice is going back and forth and how loud the talking is.

j/k about the part about how loud the talking is. =]

ideally you want the Ooma hub first in line to the modem, then the router plugged into the Ooma hub. this way Ooma has priority over bandwidth. if you put the Ooma hub behind a router and you are DLing using a bunch of bandwidth, any Ooma call will suffer MAJORLY.

as of the end of nov. ive had Ooma for 1 year now and its only been offline 2 times. once for about 15 minutes and the other time for about 3-4 hours - they must have been having some server issues, but there was never any service postings about the 3-4 hour outage.

you should have at least 1 cell phone for back up - prepaid or post paid.

theoretically it's 64K but TCP overhead means it's closer to ~80K in real terms. Not a significant difference but worth remembering.

And - OP - this is for each concurrent call in each direction

You question also depends on what type of connection you have, so how fast is your connection?

not sure really

cable, comcrap.

netflix did a bandwidth test on my tv and it came up with 4+ mbit. HD video streams fine if that's any indication.

http://speedtest.net/ Pick a couple of points near you and post back. This should be done with only you on the network, no other traffic.

Keep in mind that comcrap "limits" you yo 250 GB a month. I have never crossed it,but have gotten close a couple of times. I am not sure if they just throttle you, cut you off, or do nothing.

I only point that out since you are doing Netflix HD streams.
