Incoming callson WiFi calling goes straight to Voicemail

I love the phone and having the hardest time resisting turning the phone back in. I'm on my 2nd S3 and my third Sim card. Everything appears to be going well but I noticed that when my phone is in WiFi calling mode, incoming calls go straight to voice mail. I don't get an alert or anything. If they leave a voicemail, I get that. I searched other phones that have had this issue not just the S3. I am running stock OS but I am rooted.
Can anyone else verify that there incoming calls are working on Wifi Calling ? Any ideas on what I could try ? outgoing calls work fine.
EDIT: Sometimes calls go through, sometimes it doesn't. When it does go through, I can't swipe the green button to answer. It goes through the swipe motion but nothing happens. When I am off of WiFi calling, I can receive calls correctly and I can properly swipe to answer them

Ah-ha, you just solved a mystery for me! I like to have my phone automatically connect to any wifi in my usual hangouts to save data. I kept wondering why I was missing calls without hearing my ringtone. I have a theory on what is happening. Back on my old Vibrant, wifi-calling could not work on slower networks. I could get it to initialize but never could it actually make a call. I noticed this when up in the mountains at a lodge that had very slow internet. Maybe it's the same issue? Hopefully others will chime in.
Not sure if this a slow network issue or and ICS issue. My S3 does this also and is frustrating since I auto connect to wifi at home and work. Keep missing damn calls. My S2 started doing the same thing when I updated from GB to ICS. Maybe its a Samsung and ICS thing now that I think about it because the wife and kids all run ICS on HTC Amaze without issue.

Disappointing. Are you on T-mobile? (I expect yes as this, to my understanding, is the only US network licensed to use wifi calling?)
I am thinking of buying an S3 but I have to have wifi calling working on UK operator orange.

I think most of these threads are locked because XDA is trying to separate them all. Anyways, this is the only way I could respond. Since my first post, I have had more positive experiences with wifi-calling. I think it may be a little of both, slow connection and this newer implementation. On a slow connection it definitely wont work correctly which is what I would expect. What I mean is you can't successfully answer or make a call as the phone app will just hang. Going straight to Voicemail is another mystery altogether. I have 4g internet at home so there is no reason I can think of for that to happen. But like I said since my first post I have successfully made and answered several calls from home using wifi-calling and even a few from a location that had decent internet. Call quality was decent for what it is.
Guys, take a look at this thread. It concerns wifi signal dropping and re-enabling. That would certainly explain why some of the calls made to me when I was at home on wifi went to Voicemail even though I have 4g. I did notice some of this last week.

This happens on sprint phones as well...

I see this thread is open again. My experiences with wifi-calling have bore out what I thought: A weak signal will cause problems. I only wish that every call went to voicemail. What happens often with me is that wifi-calling will partially work, as in I can answer a call but the person can't hear me at all and I may catch one or two words from them. If they terminate the call, the phone app is fine, but if I terminate the call, the phone app hangs and freezes everything! Today it was so bad I had to pull the battery and reboot. Maybe wifi calls going to voicemail is an imperfect function that Samsung or rather T-Mobile built into the app. It kinda makes sense as this app could never complete a wifi call if you were connected to slow internet when it was a separate app. In any case I would rather have my wifi calls go straight to voicemail (and get a pop-up notification) than have the app try to work but wind up hanging my phone. What do you guys think?

I don't know about slow networks. I've already exchanged one T-Mobile S III because of Wi-Fi calling problems. My replacement works much better on my work network than it does on my home network and it is much, much slower than my home network is.

This isn't particularly good news for me. If it isn't software problem that manifests when coupled with a slow network then a future update won't fix it. That's what I was hoping the problem would turn out to be. If its hardware, then the time I have to do something about it is limited as I dropped my first phone and the replacement has a limited warranty, I think. Plus, I've paid to have invisi-shield placed on the front and back and would have to eat that cost if I get another replacement.

Epic Fail
I have this issue and am at my wits end to resolve it. Wifi calling is a major feature that worked fine(except echo) with my Vibrant. However, nothing I have tried will fix my ability to answer calls on WiFi. I have the SIM from the GS3 box. My E911 address exists since my bb8900. WiFi Power Save is off. All routers I use, Linksys E4200 and Linksys WNR1000, Linksys 614. Wireless N and G. T-mo CS could not help. I understand that the WiFi calling changed from UMA to IMS. No separate app. GS2 users with same issue. Anyone with a clue? Please help.

how did you turn off the wifi power save?
I experience the bad quality calls on wifi, at my workplace it is perfect, but at my home, its terrible.
my home network is faster than my workplace.
I think this is something to do with the firewall as well.
and I couldn't find the way to turn off firewall on the dam verizon fios actionnet router.

you can also try to broadcast the wifi on channel 3 only, that helped me in my case.

WPSM
There is a link earlier in this thread to another XDA thread. Phone app --> *#0011# --> menu button --> WiFi--> Press WPSM On/Off button.
My GS3 would drop a WiFi signal 3 inches from the router at work and 3 feet from the router at home. At least THAT is fixed now. However, I don't seem to get the same WiFi signal range as my Vibrant did using the same routers Trying the channel 3. I do have a few setting set to auto at least on my home router.

Yes, that's required, but not the underlying issue of the thread.

I've had wifi calling weirdness too. I called my sisters Verizon cell and there was no tone but after xx seconds it got her voicemail. When I call my phone on my house phone (Comcast) my phone rings but there's no tone on the house phone!

I NEVER get a ring. Just someone picks up our voicemail does.

Disable HD Voice? No ringing out OUTBOUND calls?

i have the tmobile version of the note 3. and when i make an outbound call while on wifi (wifi calling is off) it defaults to HD VOICE which has no ringing (only on some numbers tho, very strange) and it will have NO RINGING, almost as if its not dialing then someone will answer. Very annoying. So i have come to a conclusion that if i turn Wifi calling off, HD VOICE is gone and it WILL ring with those numbers that wouldn't before. But if i connect to wifi again then i get this issue. Is there a way to disable HD VOICE?
PS, i have SIM UNLOCKED the note 3 and have tested with att sim with same numbers and rings correctly whether or not on wifi, of course doesn't say HD VOICE tho
thanks a again

Anybody know how to fix this. I cant use wi-fi anymore because it turns on hd voice, grays out my network bar signal, and makes calls unintelligible. T-mobile had me disable "answer with voice" and wi-fi. She said this is a problem with wi-fi calling but I dont use that. I only had it set to use wi-fi if I left a good cellular area. That is off now too. Please help me fix this so I can at least use wi-fi again. By the way this happened suddenly on its own 2 days ago.

Did you ever resolve this?
I am having the exact same problem now.
Even though I have wifi calling turned off, if I have the phone connected to wifi it is using wifi for the calls.
Annoying as hell.

Anyone got updates on this? I just started getting bitten by this a couple months ago when I flashed from stock to DarthStalker (JB version not KK).

Any news about this?

HD voice
HD voice is set by the switch from the tower you are connected to, long story short if the backhaul from your tower is microwave and the person you are calling is on a tower that is Ethernet backhaul it won't sound right. Also if your in a Samsung owned market and the other person is in a ALU, pioneer, Ericson etc it won't sound right lastly the Samsung phones have 3 or more microphones on them for background and other noises to be muted so the over correction messes with HD calling and lastly wifi calling is using VoWifi and literally running a VPN from your ISP to T-Mobile so your bypassing the switch and hd voice isn't an option, so when you swap sim cards out the root system(boot straps and firmware for the motherboard is designed for t-mo switch and network and is wrote to look for t-mo) so the unlocked sim is just a software unlock to allow something else to be the read
---
I worked in the cellular telcom industry for years and HD calling is a nightmare, wifi calling is even worse because of e911 compliance and the fcc. I forgot to mention that if you have a phone case in like a loose fitting silicone sleeve type or the rubber shell on an old otterbox that's loose the vibration from your voice can cause static in the mic from the rubber vibrating by the charge port (old product known issue with noise cancelation on several phones)
---------- Post added at 04:41 AM ---------- Previous post was at 04:22 AM ----------
I forgot to tell you that normally when you don't have the ringing when your calling out it is a network based issue.
It could be a nesting issue(where your phone is thinking its on a tower in the next town) so with the phone on pull the sim out(if you have to pull the sim power on wait 60 seconds then power off) then turn the phone off and reinstall the sim, an issue for the market your in, the network may think that your still using wifi calling and it never fully turned it off in the network( however by simply turning the switch off it won't disable it you have to update the emergency address and look below that and choose disable( if your software is newer the platform for wifi calling by Samsung is codenamed waterpolo and there is a crap ton if known issues with it) lastly if you phone has native and Samsung wifi calling (found on the GS6/note 5 so if you have it it would be by update only) you would have to totally reset the phone and have to-mo open a network trouble ticket for a tier 3 or higher to call you back and resolve

Wifi calling Can't hear

Whenever I'm on wifi calling the person I'm calling Can't hear me. All they here is some screeching. I can hear them perfectly but they can't hear me. My wifi signal is good so is my cell signal. When I turn off wifi and use cell network to call it's fine and everybody can hear me. Why doesn't wifi calling work for me? Anybody having the same issue?

That's a software bug when the Voice Control to answer the phone is turned on. Just turn it off:
1. Go to the Dialer.
2. Press Menu then Call Settings.
3. Select Answering/Ending calls.
4. Uncheck Voice Control.
Try that and let me know how that works.

I have the opposite problem - whenever I'm on the office WiFi the caller can hear me but I cannot hear them. The home WiFi works fine. Phone is Samsung Galaxy Note III on T-mobile with Android 4.3. I checked and my Voice Control was not on, so that isn't the problem.

I can vouch for this. My boss thought I was autotuning my voice to mess with him, and a test call made me sound like Mickey mouse. Called customer care and was given the same info. It's a bug they're aware of apparently.
Sent from behind your couch while chillin with the Boogeyman!

I have a galaxy J7 on tmobile. When the phone was new Wi-Fi calling worked fine. Shortly after, the screeching problem occurred and was consistent on all Wi-Fi calls. I could hear the other party, but they only would hear a loud screech. I searched for a solution to this problem for about 7 months. I was nearing the point of doing a factory reset I just found a suggestion to turn off "ok google" I tried this and so far, no screech for 2 days.

cannot make calls via wifi calling, but can recieve texts/calls and send text help

I have a TMo galaxy s3. It is running 4.3 firmware. My wifi calling does not allow me to make calls although sometimes I can call my voice mail using wifi calling.
I can however receive calls and texts as well as send texts via wifi calling.
Cellular based calls work fine.
TMO seems to think the phone is defective, this phone is a replacement I just got and they are sending me a new one.
If the new phone experiences the same problem I am going to need some advice to fix it. I must use wifi calling in my house, tmo coverage here is terrible.

As it is, overall, I had nothing but problems with WiFi Calling over Stable Wireless. So I had given up on that. If you really have signal issues, then please see if your Router is capable of prioritizing your phone's traffic over other devices.

Thanks for the response.
Wifi calling works fine on my G2 with no issues at all.
It works fine on this S3 except for the whole making calls thing. It just instantly ends the call the second the call connects.

In that case follow part 2 of my last post.

WiFi Calling

My WiFi Calling has never worked properly, and attempts to get support from Sprint have only ended in frustration. It works fine on incoming calls, but almost always (its worked once or twice) within 10 seconds of initiating an outgoing call the call is disconnected and my WiFi Calling is disabled for about 30-50 seconds, after that WiFi Calling turns back on. I assume that something is causing me to be disconnected from the WiFi Calling server. Sprint can't even tell me who runs the server if its them or a third party). They have told me it was related to my geographic location, but I've demonstrated it having the same behavior in multiple Sprint stores on their Wifi networks. The latest is that they are telling me to upgrade to Lollipop (which I haven't tried yet). Can anyone enlighten me or anything?

I've noticed that wifi calling is flaky. Sometimes it doesn't work, most of the time it does. Sprint support was able to help me fix it one time. If you've tried to go into Sprint stores for help and called Sprint support, maybe turn it off and wait a week or so and then turn it back on....i know it sounds like a crappy answer but that's what I had to do.

I appreciate the answer, however this problem has been going on for months and it has not been "flaky" for me. All incoming calls work. All outgoing calls (with two exceptions) have been experienced what I previously described. This has been going on for many months. This problem isn't going to fix itself. Now, Sprint claims that the Lollipop release includes "enhancements" to WiFi Calling, so perhaps that might fix something. I doubt it though.
