Other person can't hear me.

I've been thinking it was a problem of slow upload speed (my DSL, as usual, has fast download but slow upload speeds) because I can usually hear the other person, but they can't hear me, or they hear me badly broken.
Is it possible that's the problem?
Doubtful - I have a 7mb upload link plus I have QOS set up and I still see the problem. Also, I can't reproduce this issue using another VoIP adapter (a linksys SPA3102) or via soft phone.
I gave up on the OBI for now as we need to have a working line, but I'll open a ticket with support to see if this can be escalated. I recommend anyone else here with this issue do the same.

I too have intermittent problems with the other party not hearing me. Also, when someone calls me, much of the time I cannot hear them say hello, but can hear subsequent speech. I'm using the Obi100 with GV.

I can't believe this thread. There are more than 50 posts, yet not a single person has taken even a modest effort to troubleshoot the problem!
It's clear that many thousands of OBi customers, the vast majority, enjoy clear phone calls. However, there is also compelling evidence that in some circumstances, the OBi is less robust than other ATAs or software, resulting in no or poor quality outgoing audio.
If we can accurately report what goes wrong, then Obihai can find the bug or weakness and fix it. In the meantime, the details will likely suggest a workaround to mitigate the problem.
This isn't rocket science. The OBi might be improperly coding the audio, sending corrupted or improperly timed RTP, having intermittent networking issues, or triggering a problem at the provider. Or, maybe it's some other issue I haven't thought of.
As a start, do you have the problem with multiple providers, e.g. Callcentric as well as GV? On both incoming and outgoing calls? When you are reasonably certain that the problem is not on the other end, e.g. calling a corded phone connected to a landline? Does it affect bridged calls, as well as calls from the Phone port? During a bad call, can you make a concurrent good call (using a softphone or other VoIP device)? Via the same provider and server? To the same destination?
Next, take a look at what the OBi is sending. Using a dumb hub or a PC with two NICs, set up your PC so it can "see" the OBi's traffic. Capture the packets with Wireshark. When you have a bad call, save the RTP in a file and listen to it. If bad, look at the payloads for clues. If good, check the stream for timing or other technical problems. If there are none, check whether e.g. a concurrent ping to the provider's server shows severe jitter or packet loss.
Of course, I have no idea what may be going wrong here; my specific suggestions may be inappropriate for the problem at hand. However, keep your eyes open and think about what may be happening. Pretend you're a doctor and determine what's wrong with the patient. Don't just report that he's sick.

FYI - for me, it's been difficult to track down as I have zero problems using any other adapter (SPA2102 and 3102) as well as the soft phone. It's just the OBI100 hardware itself that has this issue, and for me it happens on all channels (SIP1/2 and GV). I haven't tried Obitalk yet, but as I can't reproduce this issue with any other configuration it's pretty obvious at least something relating to OBI is at fault here, though for why I don't know.
You couldn't know this as you probably haven't seen my earlier posts, but I've posted a number of times with troubleshooting info and attempts to fix this issue. I'm sure at least some others have done so, too. So please don't go assuming that people are just bitching without actually trying to troubleshoot.
Stewart:
Neilio, assuming that the trouble occurs on a reasonably large percentage of your calls, i.e. it would only take a few tests to reproduce the problem, would you be willing to connect the OBi via your PC, so you could take a capture that you or someone else could analyze?
