I claim NO credit for this. Just letting you all know.
I can confirm it made a huge different for me.

1. Go to Phone and Dial ##778
2. Choose Edit Mode
3. Password is 000000
4. Go to CDMA Settings
5. Scroll all the way to bottom
6. Change Home Page, Home Orig, and Roam Orig from EVRC to EVRC-B
7. Hit Menu and Commit Changes

Phone reboots and walla no more muffed voice calls!

Thanks for bringing it over!!!

Trying it out now.

Its just an additional low bandwidth bitrate (1/4 rate @ 2kbit/s) audio codec not originally available in EVRC:

Enhanced Variable Rate Codec B - Wikipedia, the free encyclopedia


For a comparison, Vonage bitrates are:

Low quality audio = 30kbit/s
Med quality audio = 60kbit/s
High quality audio = 90kbit/s

It will basically allow for an additional level of call quality for respective signal strength...fills a void so to speak.

##778 seems to do nothing on my phone.

Are you tapping CALL after entering it?

Yes. Wonder if it has something to do with call confirm.

It does. I had to remove call confirm to access the menu, then it worked fine.

Although I didn't perform the "fix" above - just wanted to view the menu...

Disabled call confirm and it worked. Performed the fix and it seems like its a bit better. Still not happy with the weak service i have at my house.

Be warned if you are in or end up in an area that doesn't support it, you may have some issues...

I'm curious..what is you average signal strength at your house? Not the bars, the actual strength in dBm (menu-settings-about phone-network). If your dBm is -90 or higher on a regular basis, then this might help: Cell Phone Antennas and Cell Phone Boosters at Wilson Electronics

Sweet find, thanks for bringing it over. I will have to give this a shot and report back

 

[wase4711]

seemed to help a bit; will make alot of calls tomorrow, and see what people think..
lots of complaints up to this point about voice quality when I call other mobile phones..

thanks for the tip!

A little skeptical about this... Does it drain battery faster or hurt service in certain areas or incur additional charges? Why wouldn't verizon have this enabled?

 

[zeke88]

i just did this trick, testing it tomorrow

Will have to try it tomorrow.

It only adds the 1/4 rate codec, set at 2kbit/s, to the existing Full, half, and 1/8 rate codecs. Given that the "Full rate" is 8kbit/s, its not really an improvement, so much as you get to use the 1/4 rate instead of the 1/8 rate, in a marginal signal area. In that instance, it would be an improvement. It may smooth things out as the radio may not have to struggle to get the signal from 1/8 to 1/2 rate, and can just settle in the middle at the 1/4 rate.

I assume they didn't enable this out of the box because it isn't a standard yet. Probably to pass FCC they had to force revision A out of the box.

just did it.. .the jury is still out ...we will see..

Found this mod elsewhere on the forum yesterday and did it.. Seems to have made a dramatic improvement to my INC call quality...

-85 to -92 usually. Texting and such is fine. The call quality isnt that good, but then again i have a land line for calls. My daughter has the verizon network booster cause she lost calls all the time but now has great service.

Can anyone explain or confirm this?

I would like to do this but hate changing system settings that make things worse in the long-run.

I also don't notice too poor of a signal but hate knowing that it COULD be better!

I only really have issues talking to people who are using MetroPCS and Boost Mobile phones, other than that I'm fine. I did this last night and just got off the phone with my MetroPCS friend and the call really did sound much better. Now I'm really close to a tower at the moment so that could have been it too. I'll talk to her when I'm at home tonight and not that close to the tower and see how things sound.
