[Q] T-Mobile WIFI calling issue from behind corporate proxied-connection

I have no T-Mobile tower reception at work, and was looking forward to the wifi calling capability to come to the rescue with this new phone/service. Unfortunately, my work wifi requires a proxy-serverort for browser connection, and once I update the wireless connection with these settings - I am able to browse fine.
Regardless of the wireless signal strength, the WiFi Calling status states : Poor WiFi signal, before timing out with REG99 error - unable to connect. I have also noticed on this phone and the HTC EVO 4G, that while on wifi at work, my download speeds (via speednet) are high (>10mbps), but nothing shows up in the upload section.
Given the above, and knowledgeable of the fact that my corporate network does shut down access to other ports - is there any workaround to enable wifi calling behind a proxied network? I have even tried to add a new APN to include the proxyort to no avail.
wifi calling from the home network works without any issues, and yes i am rooted.
TIA for any help.

Found the solution. Turns out that accessing the proxied wireless network was the root cause of the issue. We also have access to a guest network, that interestingly does not require a proxy connection to the outside world, and that works perfectly fine!
Still unanswered then, is what ports does this phone require that are being blocked by the proxy server?

I would also like to know the answer to this. I do not have access to another wifi server to test this. What is weird though is that my Sensation that I just got rid of had no issues with wifi calling on the same network, explain that!

Automate WiFi Calling On/Off

Thanks for reading.
I am looking for a way to automate turning WiFi calling on/off. I have attempted to do this with Tasker but with no luck. I have read several threads but they seem to be referencing an older WiFi calling solution that was an app.
I am using the T-Mobile Samsung S4 w/ 4.3 and the WiFi calling settings are under Settings->My Device (Tab)->Call->Wi-Fi Calling. this phone is not rooted (corporate policy) so there I cannot use D-pad instructions to select the option.
Any thoughts?

I just took a look at the code, I think you are out of luck without root my friend. :/

I was under the assumption that it was automatic.
With Wi-Fi calling on and you're out of Wi-Fi range cellular network take over. There's a few options under Wi-Fi calling setting as to which you prefer first, Wi-Fi or cellular signal

Your assumption is correct, however if you set it to Cellular preferred and you get a call with only 10% cell signal it will come across the voice channel, and in my case most likely drop. This is when I am at the office. Conversely when I am at home my wireless coverage is spotty and I wouldn't want to use WiFi calling. So my ultimate goal is to use Tasker to turn on WiFi calling when I am at the office and turn is off when I leave. I hope this clarifies what I am trying to accomplish.

Why are you bumping all these ancient threads without adding any information?
Please don't do that.

I would like to do this as well!!!

Will it support T-Mobile WiFi Calling?

Will it support T-Mobile Wi-Fi Calling? I know Android M supports WiFi calling natively but will the carriers (T-Mobile in particular) need to do anything to allow it?
WiFi calling is very useful to me at home where cell signal is very poor.

Out of the box, at this moment, I don't think it does. However T-Mobile got it working on the Nexus 6 so I don't see why they couldn't add it with an update either before or after they ship. Think positive :thumbup:
Edit: found this from another thread in general section
"It’s also worth mentioning that*T-Mobile has already said*that the Nexus 5X and Nexus 6P should have Wi-Fi Calling support at launch. While it’s expected to be turned off by default, T-Mo has said that after you pop in your SIM and hook onto the network, you should be able to turn the feature on."

Google or T-Mobile said via Twitter or the AMA or somewhere that it does support WiFi calling out of the box, but you need to set it to be on when you get your device - it isn't on by default.
The TBD support is for T-Mobile VoLTE/Band 12, which Google said they hope will be ready to go by ship day.

Excellent. Both will help.

Do texts go over wifi as well with wifi calling enabled? At work I only have access to wifi or Sprint (because I am in a basement of a building) and it has a Sprint DAS antenna system installed. I was thinking of switching to Project Fi due to it being on Sprint's network but if texts can go over wifi with T-mobile I would probably go with them since it would open me up to a huge choice of phones in the future (I kind of want to try a windows phone sometime)

Yes, texts will go over wifi. Hurry with that Windows phone, before the platform dies completely

Here's the Twitter post where I saw confirmation from T-Mobile on Wi-Fi calling: https://twitter.com/TMobile/status/648919023158206464
The initial question was on band 12 support (hoping we get this soon), but below there's a question on Wi-Fi calling to which they said yes. This was one of the main reasons I'm switching to one of the new Nexus phones - most phones support it on their stock ROMs, but once you get sick of stock and switch to a custom ROM you have to give up Wi-Fi calling.

Question for those of you on T-Mobile...
We all know WiFi calling is enabled, BUT, has anyone seen or regularly sees any kind of indicator that they're actually connected through WiFi calling when on a call?
I have seen twice on the signal tile, it say "T-Mobile WiFi calling". But that's it. I have the setting set to WiFi preferred and I even have the T-Mobile WiFi calling Asus router, but I don't know if it's actually using WiFi calling it not.
If I have zero signal indicated on the signal tile, but WiFi on, I'll get a message telling me to connect to a wireless network when I try to place calls.
I'm also assuming that means the signal indicator tile serves a dual purpose in regards to also showing WiFi signal strength. Because when I'm on WiFi, if I switch on " cellular preferred" (in WiFi calling settings), I'll see the LTE symbol next to the signal icon in the tile, but If I switch to "WiFi preferred", any cellular symbol (LTE, H, 3G) goes away.
On a side note, if you're in airplane mode, you can't make a phone call, even with WiFi on. On my S6 edge, I could, as long as I was connected to T-Mobile WiFi calling. But the phone would let you know with a status bar icon.
I really need WiFi calling in some places at work and I dumped the S6E partly because of the 5X utilizing WiFi calling, so that's why I've wasted all you folk's time in reading this long post. ☺

Well, son of a *****, look what finally popped up...

It was enabled by default as soon as I booted with the TMO sim and ran the update.

Great to read...looking forward to trying it out when it arrives.

As was mine, but it didn't seem to want to work. I had "cellular preferred" set, but it seemed to hold onto the cell signal too much and not want to switch over. I set it to "WiFi preferred" but it still wasn't connecting yesterday. Today however, it's been all good with WiFi preferred. So it might have just been my work's network yesterday.
I still got to see if the phone will hand off the call to cellular before I leave it on WiFi preferred. I'm guessing it only will if I'm on band 12, but I'll test it anyways.

mi a2 lite wifi calling

android pie
magisk installed
voenabler installed
volte provisioned checked in phone info
wifi calling provisioned checked in phone info
wifi calling on in googlephone settings.
IMS status
ims registration - not registered
voice over lte - unavailable
voice over wifi - unavailable
turn on airplane mode, turn wifi on and I get when i try to place a call "turn off airplane mode or connect to a wireless network to make a call"
Provider is Safelink. They gave me a t-moble sim card. Already registered e911 and the link that ask for ime said my sim was wifi ready and was turned on.
Everything looks good, but I can't get wifi calling to work. Safelink customer service is useless. They cant answer if they provide wifi calling, they answer with if the phone supports it, and tell me to download a wifi app.

Tried messing around in router settings, with opening ports and ip address and enabling qos on and off. Still nothing.
Really no one can help wtf?
Anyone can suggest cheap EST usa cell service provider that offers wifi calling that works with mi a2 lite?

Try it like this: https://forum.xda-developers.com/showpost.php?p=78596219&postcount=24

Didn't work. Followed that thread and have tried everything mentioned. Says turn off airplane or connect to Wireless network.
Turned off airplane mode says. Connect to Wireless network network.
Connect to my wifi. Tried both 5g and 2.4 networks.
Browsing internet,gaming downloading through wifi connection is fine.

WiFi Calling Issues

I have terrible cell signal at home, so rely on wifi calling to make my phone function as, well, a phone. However, recently something has changed where WiFi calling no longer appears to work even though I have it enabled. Actually, that's not strictly true, it works, but only randomly and seems to not be available the majority of the time.
Previously, as I could often get 1 bar of signal, what I would do is enable airplane mode, then turn wifi back on to get wifi calling working. However, this no longer works. I have reset network settings, re-enabled and registered Wifi calling, checked with my provider that Wifi calling is available, used the Samsung Band Selection app to set to prefer using Wifi calling over cell data. I'm sure there are other things I have tried, ultimately, nothing seems to work.
Wifi speeds are good, I'm at the end of my rope with it.
It's a Sprint (T-Mobile) phone, still on a Sprint SIM here, spent an hour with support yesterday and they basically had me repeat everything I have already tried before telling me they will have to escalate it.
Anyone else having issues? Any idea what to do?
Thanks.

Not sure if this will help, but you might want to look into what port wifi calling uses and make a port forwarding entry in your modem. I just remember long ago when tmobile had their TM-AC1900 router,something about it having certain ports open to allow for wifi calling. This was before they released their 4g lye personal cellspots.....this was a wifi cellspot

These may help.....
P.s i have Xfinity for home internet and tmobile for a carrier.....my wifi calling has been weird at times out of the home while connected to Xfinity hotspots......and long story short, now that Xfinity has their own cell service they may be crippling ports....just a thought....manually forwarding those wifi calling ports should fix that if that's the case....
