Help [OFFICIAL SOLUTION]Change your vocoder settings to improve voice quality

I do have one additional question about the vocoder settings. When doing the change referenced in the link referenced above (##3282#, then edit, then advanced), I see there is a setting for EVRC-B, and it's currently set to "Disabled". Directly below that it shows the settings for Home Orig and Roam Orig, which are both set to EVRC-B after I changed them via the instructions that wega1985 provided.

Just wondering if this is another setting needed? For example, if you change Home Orig and Roam Orig to EVRC-B, should we also set EVRC-B to "Enable"??

Hmmm went and checked this out after your post good catch...anyone know about this?

Also does the Evo 4G support this setting so I can try it for friends still on that device?

That seems reasonable - I'm giving it a try. If it works, we should suggest that all three changes be made in the ##data# menu as you describe.

I'll have to go back and check what it was before - but in this configuration, my cpu monitor that I almost trust said usage went from about 10% off the call to fluctuating to up to about 60% while on the call. I've confirmed this several times.

PS - Everything old is new again - yes, it works for the Evo, yes, enabling it is the right way to go.

I made this change too, and it does appear to work. I made a few test calls and I notice better overall call quality, so far this did the trick for me. Perhaps that's the easiest route, to go (##data#), that way you can change all 3 settings from 1 menu.

##data#
Edit
Enter MSL #
Advanced

Modified Settings (Increase Call / Voice Quality):
EVRC-B => Enable
Home Orig => EVRC-B
Roam Orig => EVRC-B

DEFAULT SETTINGS (In case you want to revert back to stock settings):
EVRC-B => Disable
Home Orig => EVRC
Roam Orig => EVRC
 
I just called Sprint and their response was, absolutely not. We are not allowed to give out the MSL under any circumstances. Take it to a repair center and they will make the change for you.

Huh they gave me mine with no problem. All I said was I was on chat with a rep who gave it to me for voice quality issues and on accident I closed it out and needed it again. Gave it right to me along with MSID.

Yea that is real weird the guy I takes to said y do you need it? I told him to change some stings I can't acess without it and he read it off to me.

I would just call back and get a dif rep

Tell them your data is jacked up...whatever you try to use data all you get is error 67. Get them to walk you through resetting data. They will tell you the MSL along the way. Then just hang up! When they call back tell them "Thanks, it worked!"

Call back and speak to a different rep. I just called and said I wanted it and the lady said ok it is ______. Only took a minute once I got to speak with her.
 
Called Sprint again. Same thing. no way. this rep said they'd get fired if they knew she gave it out.

ok, no problem. I got my MSL via CDMA Workshop. All's good. time to test this vocoder thing and see if I can tell the difference.

That's good you finally got it. For anyone else's reference, if you experience the same issue then try the following. It worked for me as well as several other people, that's how I got the idea.

Just ask to speak to tech support, and say you were in your local Sprint Store and they were helping you to fix issues you were having with call quality. In order to fix it, they need your MSL so they can change some settings for you. That's all I told the tech support rep I had, and I got my MSL immediately with no hassle.

You just need to give them the impression there is a legitimate reason for you needing this #, and that your local Sprint Store is resolving the issue and would be the ones changing any settings, not you.

I have an Airave. And because I have an Airave, I can test what settings stop me from making calls.

The OP needs to be modified to add in the ##3282# step to enable EVRC-B. If you only do what's in the OP, nothing actually changes. Any perceived benefit is placebo effect. Here's how I know this:

I first only changed Home Orig and Roam Orig like the OP said. I dialed my wife and the phone worked exactly as always: Airave chime happens and then the call is placed. Call quality sounded same as usual. Not perfect but not bad.

Then I read the thread further and saw there was another place to activate EVRC-B. Call it the master switch. I turned this on, and suddenly, my phone behaved very differently.

When I placed a call, the phone would sit on the dialing screen. I hear nothing. My bars indicate I have good signal from the Airave. After about 30 seconds of nothing, my phone switches to roaming mode. At which point, sometimes it places the call (off the airave) and sometimes it just "hangs up" and takes me back to the dialer. hmmm. Sounds like NOW I'm actually using EVRC-B.

Then I read Early's posted (quoted in this post) about how someone disabled EVRC-B on the Roam Orig to fix issues with Airave. So I put that back to EVRC. Same thing. Phone tries to dial with apparent good reception, can't, and flips to roaming, at which point it sometimes dials on roaming, and sometimes it hangs up.

So... using EVRC for Roam Orig does not help Airave users. Disabling EVRC-B under ##3282# allows Airave to work, regardless of what's set in Home Orig or Roam Orig. These probably default to EVRC if the master switch for EVRC-B is still disabled.
 
I just did this and got my MSL number through sprint chat. I basically told them that I was having voice calling issues and that my local sprint store had requested the MSL number.

I called my sister and noticed her voice was much louder than previous calls. It did make a difference in my opinion. I am going to do it to my wife's evo 3d as well but will test before hand to get a better distinction of the difference its going to make.

I'm not certain on this, but from reading some other posts on other forums, it sounds as though the version or model of Airave you have may also play a role. I've read that older Airaves have more issues with EVRC-B, however the implication from those same people was that newer model Airaves may not experience any issues.

Again, I can't say for sure because I don't own one and can't provide evidence, however wanted to share as that may or may not also play a role.

That's some pretty powerful placebo effect. Wish I could use that to my advantage ;). Anyway, without really being able to test it at the moment, I'm wondering if the EVRC-B enable switch forces it or enables it. I was reading in another forum (citation needed, I know, if I can find it) that setting home orig and roam orig to EVRC-B would first use EVRC-B if available, if not roll back down to EVRC, then 13k.

I'm not denying the placebo effect. Though it sounded good when I tested it at work without the enable setting, when I got home it sounded muffled and crappy again. A friend on his 3vo (no enable setting) said his caller couldn't hear him very well. So I attributed this to my home cell site not being EVRC-B enabled.

I updated the OP and made the setting change. We'll see what happens.
 
If this actually does improve call quality, I'd highly consider getting the newer Airave (Airvana), assuming that a newer network extender would support EVRC-B. Going to go check my Airave manual (if I can find it) to see what it supports. I got mine back in 2008.

Would like to confirm which Airaves experience the lost calling ability with the vocoder change. My new Airave is an hour away, or I'd have already tested. You have to talk to customer care, who will transfer you to retentions to get the newer Airave, then you send the old one back when you receive the mailer.
 
wow, that airvana pic makes it look huge. maybe it's just a lack of scale that's throwing me off. I have the original Airave (the 2nd pic).

-edit- ah you found a better airvana pic :)
 
novox,

just to clear up any confusion, you have the first gen AIRAVE or second gen AIRVANA? the second gen has VoiP support and 3G support, the samsung first gen AIRVANA does not.

Airave= first gen
Airvana= second gen w/ VoiP and 3G support.

ill try this evcr thingy later today but want to clarify on your post novox before i do.. :)

I can confirm that after making all 3 EVRC-B settings changes that my call quality is very good now. I've made quite a few test calls since making the change, some of them were rather long in duration, and I notice a marked improvement in clarity. Great Success!!

Before this change, call quality was the only thing I wasn't 100% satisfied with the Evo3D. After making these settings changes, now I can say I'm 100% satisfied with call quality and have no gripes at all about the device. It's definitely a keeper for me :)

It actually is pretty big! I have it up in the basement rafters and it's a tight fit. Definitely bigger than the Samsung version.

Awesome. I haven't had a chance to test, really at all since the "enable" discovery. Glad to hear positive results. Agreed that this was my only gripe with the 3VO... now it's hopefully resolved.
