I recently installed Gizmo on my 770. The installation went smoothly and I have been able to make calls over from 3 different WiFi access points always to landlines I have been having a consistent problem with voice quality on the 770's side (I set the volume low and put it to my ear). In general, the ring sound when I make the call is loud and clear, but when I when a voice answers it tends to be very low, drops out, though it occassionally comes in loud and clear for a moment (a couple seconds). The receiver of the call (I only have CallOut) generally hears me well.

Has anyone had this problem and how did you resolve it - I have read of many people having good experiences with the 770.

Never had this problem in Kuwait, the US, Europe, or bits of Africa.
But then again, I have realistic expectations and don't expect it to be as good as a landline.
Both Skype and Gizmo work fine for me. Then again, I have an N800 which is slightly beefier hardware-wise.

I have similar issues with Skype and my N800. Voice often drops out and on the other side the reception is not good either. Skype test service also quite mediocre.

This was with local calls to a land line. Nokia headset used. It is certainly not an issue with my router, opened all the ports Skype suggests, but still the same results.

I've used Gizmo on my 770 with good to excellent results, better than Skype (on my PC) sometimes. That's at home with my own AP that I know is configured correctly, but even once at a Mexican hotel with wireless it worked well. My gripe with Gizmo is how abysmally hard it is to mass-enter contacts. Jeez why can't they just read a .csv file or something??

Generally speaking, Gizmo works much better with headphones than with the built-in speaker. I found that I could get landline quality with gizmo using the built-in mic and standards hearbud headphones (from a mp3 player) AS LONG AS I AM CALLING ANOTHER INTERNET PHONE.

But when I call a landline, quality is quite bad. I usually need to call phones in Europe (France or Germany), so I suppose that the problems come from poor support of those countries by sipphone.

I had issues with gizmo and German landlines as well. The other side just couldn't hear anything while I could hear the other side well and with better quality than skype.

Well, when you call someone and he cannot hear anything, it is completely useless. It does not happen always, but then it is just not reliable and I don't use gizmo to a landline anymore.

All of you using Gizmo successfully on the 770, which OS are you using? I'm using 2007HE and I can call a landline but they can't hear me and I can't hear the person I'm calling. Is this something that only works well on OS2006?

Unfortunately, solving this problem is like inventing $, it can be done, not easy. VoiP sound quality is inversely proportional to bandwidth after clearing out all hardware problems, high bandwidth, hi fidelity; low bandwidth, barely able to hear. So, you may/may not improve the sound quality, depends on whether you have max out your bandwidth by shut down all other inet/web surfing/dl activities etc and just use the 770 when Gizmo-ing!

Thanks. The headphones solved the problem. Its like night and day.

While the quality is perfectly fine now, I am not sure it is as good as a cell phone.

Cell phones get a reasonably decent call quality at 13 kbit/s...
