WiWavelength Posted December 20, 2013 Share Posted December 20, 2013 When in the the call, in the dial pad type in ##DEBUG# and then select 1X engineering. Dialer codes should not work in call since the dial pad then generates touchtone signaling. AJ 2 Quote Link to comment Share on other sites More sharing options...
gnoj Posted December 20, 2013 Share Posted December 20, 2013 I get SO 73 when calling my mother's Samsung M400- it's nice to know that flip phones also support HD Voice. That makes some sense though, since talking is the one thing such devices should be good at. Interestingly, I also get SO 73 when calling our Ooma (VoIP) landline. I know that their "HD Voice" refers to G.722, but they've discussed adding AMR-WB in the past. Perhaps they've also gone ahead and added support for EVRC-NW? Samsung engineering screens have been known to lie in the past, and I would imagine the calls have to go through the PSTN at some point, so I have to express some skepticism. The calls do sound pretty crisp though. The FCH RC fwd/rev was also 11/8 while on PCS, which I hope puts to rest any question of whether 1xA is being deployed on PCS in addition to SMR. How do you go into debug when on a call. I got on Optimus G, if it makes a difference.Sent from my LG-LS970 using Tapatalk If your phone is like mine, you can't use dialer codes during a call. I have to have the engineering screen open before I initiate the call. Edit: ninja'd by AJ- thanks for the explanation; good to know it's not just my phone!

That makes some sense though, since talking is the one thing such devices should be good at. No, I guarantee that the flip phone does not support EVRC-NW. Though CDMA1X Advanced should not be necessary, EVRC-NW seems to have gotten wrapped up in that standard. Regardless, the end point of your call should have no bearing on your codec in use. For example, the codec is not selected via a mutual "handshake" method -- à la dialup modems. As necessary, transcoding is applied in between the call end points. And any call that hits the POTS network gets transcoded to POTS quality. So, a call to an old Sprint flip phone could be EVRC-NW on one end, EVRC on the other. A call to a T-Mobile phone could be EVRC-NW on one end, AMR-WB on the other -- both support HD Voice standards, but the call will be transcoded to POTS quality in the middle leg. The same holds true for your VoIP landline. AJ 1 Quote Link to comment Share on other sites More sharing options...

If it's only a matter of what my end of the conversation (S4) supports, why are some of my calls displayed as SO 3 or 68 instead of 73?

WiWavelength Posted December 20, 2013 Share Posted December 20, 2013 Thanks, AJ I didn't even think about the touchtone. As an aside, the handset does not generate real touchtone. That audio would not pass unaltered through the low bit rate codec. Instead, signaling from the handset is used to generate touchtone at the MSC.

The network ultimately determines codec selection, and that can vary due to many factors, such as loading. AJ Quote Link to comment Share on other sites More sharing options...

AJ So the SO basically indicates network load, and whether your area is HD Voice-ready (if you see SO 73 pop up at some point), and not the quality of your call. Good to know It'd be nice if there was a way to definitively confirm whether one was on an HD Voice call, but that may not be feasible if the codec is not selected with a "handshake" and can fluctuate during the call.

Personally I'll give the benefit of the doubt to those that claim to have made HD voice calls based on nothing more than the difference in audio quality (provided they're describing a call between two HD Voice capable sprint phones). It's one of those things that you'll definitely know it's HD when you hear it. And HD voice is definitely live in certain areas, Sprint just hasn't done much to publicize it, nor have they been very clear as to where it's live and where it isn't. That said, it'd still be nice to be able to post a screen shot just for the record. Quote Link to comment Share on other sites More sharing options...

I have to have the engineering screen open before I initiate the call. I just tried this on our demo phone and it worked, same as my Note III: Make call Hit "add call" Dial "##33284#" Lock code screen comes up. Enter 777468.

I like to think of it this way...what is displayed on your phone tells you what kind of connection you would have to the switch, not necessarily the type of connection you will have all the way through to the user on the other end. If the entire connection through to the other end supports HD voice, then your call may actually connect through that way. If only your connection on the call does, then it will not.

Robert So, any idea if Google Voice co-opts that and forces things to fall back to a different codec? Of course, you might also get docked double airtime for a three way call. And, no, I am not kidding. AJ Yes, such a worry, with Sprint's Unlimited minutes or unlimited mobile-to-mobile. Or in my case, using an average of 62 a month out of my 3000.

joshnys8913 Posted December 21, 2013 Share Posted December 21, 2013 I heard the HD voice with my dad for the first time today!! I have the HTC EVO 4G LTE and he has the Samsung Note II and we were both wondering why the heck we sounded so different. It dawned on me after we finished the call.
