Thanks. Fortunately, I don't have satellite. And my ping times are usually sub 40's. But when I download, it sucks all the bandwidth up and there is nothing left of my internet connection to do anything. I guess I should enable QoS on my router so I don't mess up calls.

Definitely enable QOS.  Set your bandwidth for upload and download max bandwidth to 80% of your normal connection speeds to force your router's buffer to be the primary packet buffer on your connection.  Use speedtest.net or similar to see your bandwidth before and after the QOS change.  Then set UDP port 4500 (if Sprint WIFI calling uses the same port as T-Mobile) to the highest priority and your download ports to the lowest priority.  When your router buffer has packets waiting to be sent, it will move your WIFI calling packets to the front of the buffer and your download packets to behind everything else.

 

Your internet connection will "feel" like it works better as the traffic that you want to be quick will rarely get delayed by your big downloads. Reducing your bandwidth by 20% does not seem intuitive but it really works well once you understand how packet buffers work.  I have been running Vonage over my internet connection for over a decade with QOS in place with no issues.  You do have to watch your router CPU as QOS puts a CPU load on your router.  If your router CPU maxes out, your connection speed will drop like a rock and will be very unhappy.

I have a Linksys E1200 N300 router. I'm pretty sure it's going to strain to handle this in the long term, because I'm going to be hosting a small website on it too. In the next few months, I'll looking for another one to replace it.

My company pushed out a new Mobile Device Management profile enabling WiFi calling over the firm wifi which is awesome.

I just updated today and wifi calling got off to a rocky start, first with choppy voice (my internet is fine I use our VoIP landline on it all the time with excellent results) and then another call dropped 15 minutes in.

 

I noticed that SMS over wifi is not enabled.

 

Also as far as voice codec goes it sounds like G.711 to my well trained ears, which is definitely not what T-Mo is using. (AFAICT)

What codec is T-mo using? G722?

I honestly don't know, but on an iPhone 6 I used last week it definitely didn't sound like G.711. It may have been one of the AMR codecs maybe? That's my suspicion based on how it sounded, and would make sense considering it's supposed to be able to handoff to cellular whereas sprint clearly said there's "would most likely fail" to handoff. (And I don't see how it would handoff from wifi to cellular since I thought T-Mo was doing the handoff from VoWiFi to VoLTE and not to the circuit switched network which is all sprint has.)

Just found out a big negative for WiFi calling for me.  

 

I use YouMail, and when WiFi calling is turned on, VoiceMail goes through Sprint's voicemail system instead of YouMail's.  I tried the Activate YouMail phone dial sequence and got an audio message that that feature doesn't work when using WiFi Calling.

 

So I'll have to keep WiFi calling off under most circumstances.

The other thing is "iPhone cellular calls" doesn't work with WiFi calling enabled. (that's the setting so your calls go to other iOS devices too) 

Not a huge deal for me as I didn't use it that much but was convenient. 

 

So far the WiFi calling has been on and off choppy, like a crappy SIP call. I've never experienced this with T-Mo wifi calling, not two years ago and not last week on a friends iPhone 6. Though not surprised that Sprint's is having trouble, because afterall, it is Sprint...

Free international roaming and learning about WiFi calling the same day, say it isn't so!

After further contemplation - I really have very little need for wifi calling.

 

There is tower that is part of Project Ocean in our town that is not live yet - but it will solve 99.9% of my Sprint coverage issues. I literally will have zero use for wifi calling once that tower goes live. That's how good Sprint coverage has been for me personally..

 

While I do think it would be neat to have for traveling out of the country - my normal travels around the continental US really have little to no need for wifi calling.

 

I just wanted it because the android guys had it. ????

Well now we have it, and I like continuity calling too much, plus my internet connection drops out far too much to use wifi calling for now. Very unreliable ISP lately. Too bad they can't fix the antenna I receive my signal from.

I just disabled mine too. The wifi calling has been nothing but garbage since I got it yesterday, caused nothing but problems. Most of my outgoing calls failed with a fast busy until I disabled it and now alls fine again.

It seems that you all are experiencing issues that I have not. I have actually enjoyed it. Quite clear.

Had a pretty serious issue today and my troubleshooting seems to point to WiFi calling on iPhone.  Today trying to call my Wife who also has an iPhone 6 I kept getting a fast busy signal or going straight to voicemail.  Calling other numbers was generally successful but would sometimes get a fast busy also.  Folks calling me would sometimes get a busy signal or go to voicemail.  Other services such as texts and internet seemed to work fine.  These issues were happening all over town and not just on wifi. I turned the WiFi toggle off and still had issues.  Finally logged onto my acct and removed the WiFi calling provision from both of our lines.  No issues since.  So if anybody with an iPhone is experiencing call issues you might want to try this before taking more drastic measures.

I can confirm the same issue here. I toggled it off, logged on to my account and removed the provisioning, and all is well now. This is a big bug, what a headache.

Thanks for sharing. I did a support chat and reported it. They had no solution when I called them still having issues. They wanted me to do a wipe and restore as new but I tried removing the provision before doing that and it worked. What is weird is it worked well for a couple of days and today I had the issues. Luckily I have good service at work and home so this is not a huge issue for me right now.

Me too. I don't even need WiFi calling, I just wanted to try it because it was something new. I'll leave it alone for the time being. Hopefully it's not a widespread problem, lots of mutual confusion and head scratching otherwise.

iOS 10 will bring updates to WiFi calling on Sprint that allows SMS over WiFi and lets you retain the ability to have HD Voice while WiFi calling is activated on your line. It currently works on the iOS 10 Beta and is much better than before, IMO.

Sorry, when you say "retain the ability to have HD Voice while WiFi calling is activated on your line", do you mean that the phone can do HD Voice while on cellular and WiFi Calling is activated (but WiFi calls are still non-HD) or does that mean that both cellular and WiFi calls are HD?

I haven't noticed that yet, activated WIFI Calling and lost my HD Voice. 

 

Will wait till iOS 10 Official just to be on the safe side.

You retain HD voice when WiFi calling is enabled, while on the cellular network.

I've got the iOS10 GM installed on my 5C and it will not do SMS over Wi-Fi calling. Has this been documented anywhere?

It should. Go to settings>general>about and scroll down to the "Carrier" field. What does it say?

      I don’t know if anyone has already posted information about wifi calling, so I thought it would be good to add this.  In the last 2 weeks, I posted on the sprint.com forum and the Sprint reps were unable to answer the simple question of what port does wifi calling use. Previous to posting I called customer service and Airrave support and no one could answer either. I didn’t expect a detailed answer, but they could have called someone who knew the answer.  Anyway, two very knowledgeable users on the forum narrowed things down, and wifi calling uses UDP port 4500. I had already narrowed down the ports to a handful, since I found information on the web about TMobile’s similar wifi calling. Also, I found a netstat option built into my Asus RT-AC66U router that was helpful for looking at ip/ports for our phones. The Sprint server the wifi calling traffic heads to is 68-31-26-1.pools.spcsdns.net  The reason I started asking about the port and connectivity is because we experienced many calls that would either drop or when you called someone it would go silent during the call. This goes along with UDP traffic being connectionless and sensitive to any disruption.  I prioritized traffic for our GS4T and GS5 phones for port 4500 and found there was a firmware updated from Asus for the router that helped.  Also, I skimmed over (on some other android forums) the updates for the GS5 to android 4.4.4 and I noticed something with wifi calling bug fixes.  I am happy to say that the wifi calling is working a lot better now.

      So, we all know about the lovely iPhone 6 and iPhone 6 Plus User thread, and there are many different device focused threads across S4GRU, but there are none for us older iPhone users. So, why should they get to have all the fun? This thread is dedicated to anything and everything about our beautiful (Spark-less) iPhone 5's and 5S's.
       
      Discuss anything like jailbreaks, hardware problems, how much you love your device, how great it is to have at least one LTE band compared to the folks who still have 4's and 4S's, ask questions and maybe you can get some answers, etc. etc.
       
      Discuss!

      I know someone on here might be able to help, but I have a Sprint iPad mini (1st gen) and I have been swapping between my Sprint SIM card that came with the device and a TMobile SIM. This past time when I reinstalled the Sprint SIM I was able to purchase data, but then the reprovisioning kept failing. I cannot use the data. I tried resetting the iPad completely, and that did not work. I restored the iPad as new and that also did not work. I also noticed that the iPad kept going from Sprint 3G to 1x over and over, even in an area with full LTE. I called Sprint support and they said that they could not handle anything prepaid (which was shocking), but when I pushed a bit on them, they helped troubleshoot. Still, nothing has worked. I will call Apple this evening if nothing else, but I am traveling for Memorial Day, so it would have been nice to have extra data on the iPad. Anyways, does anyone have any thoughts? I am thinking it may be a hardware issue, but it does not appear to be a SIM card issue. Still in the car on a long trip from NYC to Ohio for a wedding reception and visiting the in-laws.

      With the FCC and Sprint, T-Mobile, AT&T and Verizon have agreed to this new unlocking policy. How does this effect sprint phones such as the IPhone. I have heard that Sprint can unlock your phone but you can not take it to other carriers such as Verizon and the IPhone can only be used overseas.  (Correct me if I am wrong). I am glad that this has finally happened. But when it comes to Sprint how would this work?
