The other person can't hear me for 30 seconds
Continues to happen, both morning and evening. For what it's worth, I'm using Comcast cable. Speedtest shows about 6Mbps down and 5Mbps up. Ping is about 25ms. My own QOS is set at 2458kbps for up (based on past tests) and default (0) setting for down. My ooma telo device is running with revision 1.36111.

Re: The other person can't hear me for 30 seconds
What kind of tests? Most speed test results are distorted for Comcast due to Powerboost, so your setting may be too high if your subscribed speed tier is 2 Mbps upstream. If you are on the 12/2 or 16/2 plan with Comcast, try setting your upstream QoS lower, about 1600 Kbps.sniffbert wrote: My own QOS is set at 2458kbps for up (based on past tests)

Pointed Ooma tech support to this post and he is looking into this issue for everyone.
Re: The other person can't hear me for 30 seconds
Not sure if it is the same problem but when I make a call, the other person can not hear me.
I unplug the Ooma and then plug it back in and things work fine for a while but then I'll call someone and they can't hear me again.

Sorry about the delay. This weekend, I set my uplink QOS to 1600, but unfortunately the problem is still with us.Groundhound wrote:What kind of tests?

Curious if there is a respected site for gaining performance information. Many just provide data to/from the closest location. Wouldn't it be better to verify data to/from the ooma server? How?

Re: The other person can't hear me for 30 seconds
Please add me to the list. My brother got very frustrated speaking with me last night as he couldn't hear me several times during the call. I told him that I was generally happy with Ooma, but this is unacceptable. I tried to reconfigure Quality of Service, but I don't think it changed things. Why this all of the sudden?
Re: The other person can't hear me for 30 seconds
Not sure how your VoIP quality tests look like. But you can also check Cable Modem if your ISP is Cable.

Packet loss should be 0.
Download and upload QOS should be at least 70%.
Maximum TCP delay should be under 100 ms.
Try this. Connect to the status web page in your cable modem
http://192.168.100.1
Find the downstream and upstream power in dBmV and the Signal to Noise Ratio (SNR) and report back.
The downstream signal power should be between -10 and +10 dBmV. (Some say between -15 and +15 but I feel that is pushing your luck)
The SNR should be 35 or more.
The upstream power level should be less than 55 dBmV.

Here is everything available from my Cable modem (Motorola Surfboard):
Downstream Value
Frequency 687000000 Hz
Signal to Noise Ratio 27 dB
QAM QAM256
Network Access Control Object ON
Power Level -7 dBmV
The Downstream Power Level reading is a snapshot taken at the time this page was requested. Please Reload/Refresh this Page for a new reading
Upstream Value
Channel ID 10
Frequency 29600000 Hz
Ranging Service ID 5633
Symbol Rate 2.560 Msym/s
Power Level 45 dBmV
As far as whichVoiP readings, some things look good; others look very bad. Interesting ... if this has anything to do with it, interesting that it happened to many different people, all about approximately the same time.

Re: The other person can't hear me for 30 seconds
Previous poster said ooma support would be investigating this problem. I haven't seen status from ooma. It would be nice to know if you're reading this, even if you don't yet have an answer.
Re: The other person can't hear me for 30 seconds
The packet loss and TCP delays don't look too good. The Signal to Noise ratio is low too. Hopefully murphy & others can chime in with some corrective action suggestions. Minimize cable splits, etc. But here is a good read.
A family member had intermittent issues with call quality and these tests would look fine most of the time but once in a while would go belly up. Turns out, it was his modem. With a new modem, his problem was all fixed. If you lease the modem, get a different one and test it out. If not, try to see if other corrective actions would improve the situation first.
