This forum includes tips for maintaining the best audio quality possible with the Ooma System. If your Ooma system is having issues with dropped calls, static audio or echo, look here for assistance.

We are having call quality issues and have had them for the past month. Bandwidth is ample: 2Mb up and 1 Mb down (tested). iperf to ooma indicates 1059 for bandwidth.

Get this: when on a call that gets garbled, the simultaneous iperf to ooma reads only 159. Upon immediate disconnect, it jumps back to over 1000. If I run an iperf to a different server on the ISP, I get over 1Mb without being on the call, I get 850kbit when on the call.

The only conclusion is that the bandwidth issues that are causing voice quality problems are related to the ooma network and not local. If someone here is with ooma and wants to diagnose where the breakdown is occurring, I am willing to work with you. I am with the ISP, and can run tests others cannot run.

Here is an update. My Telo is still on 49339.

I had an Ooma employee really help out. He said:
I think there may be an issue with the Telo's redundancy algorithm for certain connections. I've disabled the redundancy algorithm on your Telo. Can you let me know if you continue to hear robotic voice on your calls?

Mr. Roboto has gone away as a result. We have had some audio drops (which we have not had before which sound like a system freeze) but they are few and far between, and I am not convinced that it was not something we were doing on our systems at the time.

So, does the new firmware help? I do not know. But if not, I think this should be a GOOD lead for Ooma as to what the real problem is. [My MajicJack Plus is sitting around almost unused as we keep our Ooma]
