According to the subreddit, the Note 7 currently lacks wifi calling because they're waiting for next month to launch the new IMS APN, which could mean we're getting closer to an official VoLTE launch.

Closer? I guess it's all relative. 

We are getting closer to 2018-2019 after all.

Your saying the note 7 will possibly be one of sprints first lte devices?

No but the fact that Sprint will have an IMS core means they will be ready to power the VoLTE system when they're ready to flick the switch.

Wow we are really getting closer now. So Sprint never did have a IMS before?

I would very much like to see an IMS (IP Multimedia Subsystem) fix.  It is a required step on the way to VOLTE for Sprint phones.

 

iPhones have had a SMS problem since Sprint WiFi calling came out where they cannot send or receive SMS messages while on a WiFi network without macro network coverage.  They can send/receive iMessages while on WiFi and will try to switch to the macro network to send/receive SMS/MMS messages.  This means the problem does not impact many users while on WiFi calling but it is a deal breaker for VOLTE and may be the primary reason why Sprint is the only one of the top 4 that does not offer VOLTE.  This does not appear to impact most Android phones but possibly this new Note 7 is impacted by it.

 

You can see the IMS problem on iPhones in Settings - General - About.  Click the Carrier line a few times until you get to get to IMS status and you will see that only voice is enabled on the Sprint network.  IMS must be enabled for voice and SMS to properly use VOLTE in the future.

The new IMS is live. In the latest iOS 10 beta, voice and SMS both work over wifi and the new APN can be seen in field test.

Doesn't this also open the door to wifi calling to macro network handoff and back?

Hopefully this is a step toward Nexus devices finally getting WiFi calling too.

I don't believe wifi to macro is possible without VoLTE (but there are rumors of a sprint VoLTE launch in mid september). Kind of funny how wifi to LTE handoff is possible and LTE to CDMA handoff is possible (with SIB13 on the network) but wifi to CDMA handoff is not possible (at least as far as I know).

Sprint will not "launch" volte til 2018-2019. Whatever rumors you heard is wrong.

I thought VoLTE handoff to cdma is problematic and that's why Verizon never introduced it, and the same reason why Sprint is waiting to densify before I'm poo implementing VoLTE.

Sad truth, but maybe they could start a very long opt-in beta in September. One could hope...

Just rumors. No official source. Chances are it's not true but you never know I guess.

Sprint is not even close to being ready to launch VoLTE nationwide.  The Sprint LTE network still needs lots and lots of work before even considering VoLTE.  Once Sprint has a tens of thousands of small cells up and running as well as upgrading as many macro sites with all 3 LTE bands can they start to think about VoLTE.

This.

 

Basically, Sprint has to deploy enough small cells to cover any LTE coverage gaps to match 3G/1X coverage. There's no fallback with VoLTE and CDMA, so if LTE drops, your call would drop. At a time when their calling reliability is at an all time high with 1X Advanced, they would not want to hurt those numbers. Even with 800MHz LTE in my area, it's still no match for CDMA. Sure it can match/beat EVDO, but not CDMA.

 

If Sprint does release VoLTE early, I'm sure it'll be opt in. Then people could choose between less reliable VoLTE (with simultaneous voice/data) or more reliable CDMA HD calling.

Ok so I've confirmed that there is some form of SRVCC running on Sprint's network as of today. Today, as I left a friends house, a call I was on handed off from a wifi call to the macro network without dropping. It didn't occur to me at the time but I messed with it a bit later and found that the call handed off successfully from wifi to the macro network about 90% of the time. Also btw I have an iPhone 6S. I took a video of this happening with my ipad although I am not entirely sure how I should upload it. If anyone has any suggestions or comments I'm all ears.

Yep. Wifi calling to network soft handout has been in the works for a while.

    • I definitely don't need more coverage... just the damn VoLTE activated so I can get calls and MMS at the same damn time. Like I said, it isn't a huge deal, just annoying that this is even a problem in the first place. They told me AR4 are out of stock and they have no idea when they'll be back, nor can they put me in touch with someone that knows. They said they just have to keep checking and see if it comes back in stock. Once again, I said that is nonsense, but what can I really do about it. For right now, the Pebble boosting the LTE, and using wifi calling, is working fine for my needs. Much better than the AR2.5 I was using which didn't work at all.
    • Yeah VoLTE took forever on Airave 4s, but it's definitely working now. Supposedly it was enabled months ago, but not necessarily for existing devices (only new ones). I had to factory reset mine to get it back in the queue, but after 2.5 weeks it got it. My Magic Box with wired backhaul, on the other hand, got it only 3 days after a factory reset. It seems that a lot of femtos setup before VoLTE launched never got put back in the queue (particularly femtos using WiFi or Ethernet backhaul), hence the necessary factory reset. I'm not sure if an Airave 4 would offer substantial coverage improvement over the Pebble, other than having CDMA as a fallback. If you need to cover a larger area, you can use both actually. They should handoff to one another with VoLTE, just keep them sufficiently far apart to minimize interference. And you'll probably have to tell Sprint it's for use at a different address, but they won't actually check where it's deployed. Sent from my Pixel 4 XL using Tapatalk
    • Do it quickly.  My impression is T-Mobile really wants to move people to their network ASAP, even if it causes lots of pain. August 1 is rumored to be the end of Sprint retail.
    • I'm trying to switch over to the Airave 4 now that the've enable VoLTE on them. That should fix this problem. The only reason I got the Pebble over the AR4 is because VoLTE wasn't enable on it yet.
    • My router typically only gets rebooted for firmware updates or major functionality changes that I have implemented. Otherwise stays up for years.  Last time it was down is when Hurricane Ike remnants hit Ohio in 2008 and caused week long power outages, which killed local internet in a few days (I have two ISPs, UPSes, generator).  ISP's battery backups and generator use had improved considerably since that time. Making changes appears to be the greatest reason for router instability. So put internet connections on a UPS,  reboot after major changes, and otherwise enjoy.
