I am having a strange problem with incoming calls.
The voice quality is very bad with the other persons voice being "metallic".
However, no such problems in outgoing calls, and other people can hear my voice fine.
I called up my network operator, and they tell me I need to switch off "Clear voice" setting in my phone.
However, I went through all settings, and there is actually nothing with this name.
So is there such a setting?
If not, can I try upgrading to latest firmware. Actually, I have not updated my froyo (I am still on 10b), as I do not want to loose capability of rooting.
I think latest is 2.2.2 (10e). I am not sure if its rootable.
Any ideas?
I don't think there is such option in optimus one, try to switch to 3g network if you use 2g, but compared with other phones my optimus one output sound quality is bad. I don't think that you can do anything but if you find a way to improve sound quality let me know.
do you experience background static noise? because I cand hear a background buzzing noise everytime the sound is on.

Ask to talk to someone technically savvy who knows WTH are they talking about next time. There is no such thing anywhere and frankly I do not recall any mobile phone that would have such thing like "clear voice".
2g and 3g have nothing to do with voice quality... oh, and the background static is a bug of all O1s, unfortunately.
Voice quality is dependent on the price of the device, so a budget phone generally means poorer quality... only Nokia had perfect reception on their low-end models... just my 2 cents.
Maybe that operator got his features mixed-up and he was referring to HD Voice - I know Orange launched it in a few countries, but that's a whole other thing.

Ah, speaking of HD Voice, do you think devices NOT bought from Orange could use it?
Also, have you noticed that, during calls, there seems to be some form of noise reduction going on? If the person you are talking to is in a quiet(er) environment, and they stop talking, the speaker goes completely silent, whereas when they are talking you can hear the normal (IMO) GSM background noises.

Actually, many devices support it at this time, since it's a codec-related thing and not a hardware one (and it's not proprietary to Orange, it's a standard that will be implemented in time)... It's rather tricky to make an assumption about your O1, since I really have no clue if the appropriate codecs are included on our phones, if they are activated etc.; just ask someone from Orange (although I'm sure that most will not know the answer).
Here's a very interesting article detailing HD voice tech, written by Eldar Murtazin: http://www.mobile-review.com/articles/2010/hd-voice-en.shtml.

Yeah, that's normal, I have encountered it on many phones... it's probably related to the passive noise cancellation algorithms our devices use (where they try to make out what part of the sound received in the mic is the voice and which one is the ambient background). It's a really long discussion, since when the mic receives a sound lower than X dB it cuts it out, then as soon as it detects a more powerful sound it applies a kind of gain (hence the static) and so on.
Oh, note that these are all more like educated guesses, but I think they're pretty correct.
Now, with active noise cancellation... well, that's just another world! (I had the pleasure of a few conversations with a phone that supported it)
There is no static.
Its just that, from some networks(not all) when I get incoming call, the voice is "metallic" and keeps breaking, even when signal is full.
So its impossible to have a conversation.
I guess its a problem with my network operator then.
In Hidden Menu (3845#*500#), under
DEVICE TEST->SOUND TEST-> VOCODER are the settings that affect noise reduction and bad call quality but I do not know what parameter disables sound processing on calls.
Also on page no.55 in service manual, there is this text and I hope that it can be useful to someone with greater knowledge to change parameters and turn off noise suppression, and that stupid hiiiisss sound during call.
3.13.2. Audio signal processing & interface
3.13.2.1 MSM7227 audio interface
The MSM7227A audio front end comprises the stereo wideband codec, PCM interface, and additional DSP
audio processing. The stereo wideband codec allows the MSM7227 device to support stereo music/ringer
melody applications in addition to the 8 kHz voice band applications on the forward link.
In the audio transmit path, the device operates as 13-bit linear converter with software, selectable 8 kHz and
16 kHz sampling rate. In the audio receive path, the device operates as a software-selectable 13-bit or 16-bit
linear converter with software selectable 8 kHz,16 kHz, 22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz, or 48 kHz
sampling rate. Through software, the Rx path can be configured as either a mono or stereo output. New to
the MSM7227 device is a transmit (Tx) ADC path that now supports stereo wideband sampling. The
integrated codec contains all of the required conversion and amplification stages for the audio front end. Th
codec operates as a 13-bit linear codec with the transmit (Tx) and receive (Rx) filters designed to meet ITU-T
G.712 requirements.
The codec includes a programmable side tone path for summing a portion of the Tx audio into the Rx path.
An on-chip voltage/current reference is provided to generate the precise voltages and currents required by
the codec. This circuit requires a single capacitor of 0.1 μF to be connected between the CCOMP and GND
pins. The on-chip voltage reference also provides a microphone bias voltage required for electret condenser
microphones typically used in handset applications. The MICBIAS output pin is designed to provide 1.8 V DC
while delivering as much as 1 mA of current.

I just recently got the new Nexus 4 and have been playing around with free SIP calling. I got everything working with PBXes.org and Csipsimple, but I'm noticing the audio quality that the people I'm talking to is really bad because of PBXes.org poor codec support (all are 8khz boo). Are there any other SIP providers that let you pair to google voice and support at least some 16khz codecs or G.729 for free?

From my research, the best codecs for mobile data connection are G729 and iLBC.
I found a way to use iLBC codec in pbxes for free in/out Google Voice calls.
http://forum.xda-developers.com/showthread.php?t=2057887
There are other solutions but suffer one of the following
1. not free
2. can't use the same number for in/out calls.
3. battery hog
4. requires a private asterisk server.
I'm currently using groove ip lite to make a few calls a year to the US from canada. My issue is that it it only uses the G.711 codec, so I'm screwed if my 3g is spotty or my wifi is congested.
What I'm looking for is a relatively easy way to use the speex codec or another codec that copes with jitter and scales well with either gtalk or something else free/cheap for these canada <-> US calls.
Thank you for your time.

If you want to make calls through Google Voice (to phone numbers) the issue you'll run into is Google Voice only supports the G711 codec. Anything that connects directly to Google Voice will only support G711. If there's another server involved then between the app and that server can have a different codec, such as if you used a SIP service. But at that point the SIP server would have to translate between codecs to G711 since all traffic to Google would be G711.
If you just want Google Talk calls you can use the Google Talk app. But that can't call phone numbers.
I need to call phone numbers, what are my options?
Hi guys.
I am searching for many days about this, but still no proper information.
(Old sony ercisson and nokia mobile had video calling feature.)
Why there is no default video call app in android?
(Ref: http://en.wikipedia.org/wiki/List_of_features_in_Android )
Why there is no App in market or any module for Xposed framework to enable video calls in droids.
Where some manufacturers have video called function enabled and Korean mobiles (LG, Samsung) has video call function but that doesn’t seem to work in Europe, Asia or America, it works only in korea.
Now I have few queries.
1--> is it possible to make video call from any android via any kind of customization with rooting, installing apps or with xposed framework etc.
2 -- regardless of unable to make video call, can droids receive video calls?
3-- is it possible to make video calls with Korean android mobiles, outside Korea? Or we can say, is it possible to fix this error, “when global roaming, video call not supported”. Or it is possible to enable video call when roaming.
Fronts cams are 50% useless without native video calls in androids, why nobody is trying to add video call feature in android?

you didn't read first post ? video you post, everyone knows about these apps, i am talking about 3rd data apps, my question was about video calls over cellular networks.
sorry man
it must be include your rom
It's called hangout. Google hangout
hangouts video calls are on data, not on cellular network
Does anybody know if RN4 esp. Mido/Snapdragon variant supporting HD Voice (Audio-Codec AMR-WB) or maybe even HD Voice+ (Audio-Codec EVS) for telephony/calls ?
The question arises if this is supported by hardware and which ROMs support this ?

Dont ask me why it's disabled, this phone is truly "made in China". (fun fact: HD Voice works on MTK variant)
You can try to just add "ro.ril.enable.amr.wideband=1" in build.prop but i dont think it's gonna do anything.
I found out that VoLTE uses either AMR-WB or EVS codec. So if VoLTE is working it should use HD voice.
This hack is for HD voice over 2G/3G

VoLTE works, but it has nothing to do with HD Voice (which is 3G technology), VoLTE is LTE technology.
If VoLTE doesn't work for you then you better contact your sim carrier.
