Calling 1-800-GOOG411 results in bad call quality. I hear a lot of static and crackling. I call other numbers and the quality is fine. I call other 1-800 numbers, the call quality is fine. Any clue on what might be going on?

I have the Ooma Telo inbetween my cable modem and router. QoS on Ooma is set to 0 for both up and down. With my ISP I get 30Mbps down/6Mbps up. I also tried setting the QoS upstream on Ooma to 6144 ...but I have the same problem.

Google carrier kind of sucks sometimes. Bandwidth.com?

Thanks for the responses.

Tried making some calls throughout the day today to various numbers. Call quality was TERRIBLE - very choppy at best.

My setup is per recommendation. Ooma Telo is between my cable modem (Cox communications, service is 15MBps down/3 MBps up, measured 25+ MBps down/6+Mbps up) and wireless router (ZyXel X150N).

Don't know what to do next. My colleague has Ooma and says his line quality is better than landline. Perhaps it's my Internet provider? Regardless, looks like I will have to go back to my regular telephone company. Might try to call Ooma support tomorrow.

VoIP doesn't seem to have reached a quality level enough to justify replacing a landline for residential customers.

Here's the output from which voip. Does the 58% download QoS mean that I will have choppy audio - that's what I'm experiencing right now.

Try the competition. Microsoft's equivalent service is 1-800-LIVE411
