just set up new Tmobile home internet in a rural area-all carriers are iffy here but the Tmobile speed and connection are ok at home (not so much in some communities near me). That is the issue-I have my cell service on Verizon (best coverage all communities) and it will not connect a wifi calling attempt. All other cell services work flawlessly and if I use a different sip the wifi calling works on the phone. I have tried a different router (actually 3 of them as well as mesh system all with the same results-internet traffic is good and no wifi calling) I would like to resolve this and continue with Tmobile but without wifi calling its not helpful-any suggestions?

After spending half the day with the Sagemcom gateway 1.2.74 firmware and making several phone calls with WiFi calling enabled across multiple phones in my household, I can comfortably say that my WiFi calling issue has been resolved. I do hope the firmware update will resolve everyone else’s WiFi calling issues. I did not know how much I depended on this feature until I found myself without it. Good luck to everyone in the same situation!
Did you test receiving calls?
Yes, everything works as it should with the Sagemcom gateway 1.2.74 firmware. Initiating and receiving calls with WiFi calling is stable and reliable.
On a side note, my uptime without a WAN002 error (requiring reboot) is now 11 days and counting.

That is because your phone uses Verizon. And Verizon is a cdma carrier, and wifi calling does not work on cdma networks. You must have a cellular service that is a gsm network like T mobile is....
Actually, Verizon and AT&T as examples, use their own implementations of WiFi Calling and VoLTE that differ from the stock Android imementation designed by Google.
Well, I got it last night (in the wee hours) and it looks like the Sagemcom gateway 1.2.74 firmware update did the trick. WiFi calling seems to be working fine now. I hope everyone who needs it gets it soon.
Same problem as everyone else. Just got a new T-Mobile gateway for home internet. Internet speed is great and has 4 bars in its current location. Wi-Fi calling will sporadically work but not reliably and it will drop calls. It worked perfectly fine with my Comcast router using the same phones. Both iPhone 11 and iPhone 13 Pro experiencing the exact same issue. I have turned off Wi-Fi calling because it is more reliable even with 1-2 bars in my house, but I wish this would be fixed. After a year of this issue being overlooked, my guess is we’ll live with it or move onto another service provider.
We’ve had the 1.2.74 update now for a couple of days, and can happily report that the WiFi Calling feature is now working on our iOS phones. Thank you, T Mobile!
Will continue to evaluate the new feature performance over time and report any issues here. But so far, so good.
I'm also glad that I found this thread. T-MHI, Pixel 6 Pro, Pixel 7 Pro, iPhone 12 Mini... WIFI calling won't work and we need it. TM has been covering towers in our area and the indoor phone service has dropped to nothing.
Two visits to stores and two very long customer support calls where the did vague things like remotely "resynchronized our phones" did nothing. Everyone I spoke with seemed to have zero knowledge of this issue.
I asked about a cell-spot to boost my cell connectivity. They said that it wouldn't work because the cell booster they use actually connects to wifi to work and it isn't compatible with the TMHI. I said, "Maybe that is also why WIFI calling isn't working." He said, "We are kind of getting into the minutia of this, all I know is that won't work for you. Let's try some things I can do like Resynchronizing your phone to the network."
None of that worked.
Side note that others have also mentioned... My work phone is a Samsung S22 FE and it WIFI Calls Just fine through my TMWI. ???
Yesterday, I moved two of my 4 lines off of T-Mobile and on to Verizon. Still no WIFI calling, but the cell service is a little better in the house.

WiFi Calling doesn’t work too well with mesh systems, because that established connected can’t be passed around so easily. WiFi Calling also requires a reasonable amount of bandwidth, both up and down. QoS doesn’t adequately handle WiFi Calling well. If you have 20Mbit up and more down and there isnt’ anything sucking up the rest of the bandwidth of the network. It should work. I have never had any issues getting WiFi Calling working with Asus routers. I have owned 2 Asus RT-AC66U’s, an RTAC68W, and am currently using 2 RT-AX86U’s without any issues.
Can’t believe my luck…I guess I’m never getting WiFi calling 💀
I am in a rural area with the same issue, internet runs great with the Home Gateway, but cannot make wireless calls from my Verizon phone. Has anyone found a solution to this issue?
So, looks like TMO updated the firmware from 1.1.51 to 1.1.52. Still no WiFi calling. Does anyone know what they changed?

We have the Nokia 5G Gateway N1 with iPhone 12s on T-Mobile. Just about every call will fail after 1-3 minutes, very frustrating as cell coverage is a couple bars LTE at best so we relay on the 5G home internet. Home internet is blazing fast by the way, no complaints there.
WiFi calling worked fine for about a year after install but has been failing since last part of 2022.
A T-Mobile tech support rep told me they have some firmware issues on the 5G Home Gateway that is causing WiFi calling issues.
I am in the same boat - getting about 15Mbps on the 5G gateway 5Mbps on Verizon work phone. Calls not going through to work phone if WiFi calling is on.
If I turn off WiFi calling it somewhat works if I go outside - no fun in the rain.
Hmmm I have the same issue, no Wifi calling over the sagecom home internet, well I can call out but not receive calls. I was going to call T-mo for the new firmware but then I read about the bricking issue so I guess I will wait for them to fix the firmware.

Any updates on this? We just got the 5G home internet and it’s fantastic! But the Wi-Fi calling issue is just that… an issue. We use Cricket Wireless which runs off of AT&T
Jeez. I was on the phone with home internet support and prepaid support for hours working on this tonight. The usual phone ping-pong. I installed the Sagemcom router yesterday and my GF couldn’t call me since when I was home and on Wi-Fi. Stumbled across this thread just as I was about to give up. My FW is 1.1.52, so hopefully the update will hit in the next few days. Otherwise a great service.
This thread has been going for a while!
I’ve googled this issue for hours. Is there a fix?
The engineers were aware over a year ago and haven’t addressed it?
My Pixel 6 on T-Mobile is unable to use Wi-Fi calling when connected to the newest Home Internet Gateway (Sagemcom Fast 5688W). I've been using Wi-Fi calling with multiple phones, on multiple Wi-Fi networks, all with TMo cell service since 2007. It worked perfectly on Spectrum. Since switching, I'm not able to receive calls using Wi-Fi calling. I had to "toggle off" Wi-Fi calling and then...all is right in the world again. It doesn't work when I use my personal router plugged into the Gateway either. A next level TMo customer service guy checked everything he could from his end and confirmed that "all was as it should be" and said they were unaware of this being an issue. I'm guessing this can be fixed with a Firmware update. Can I live without it? Sure, but shouldn't it just work? I wish TMo would pass this thread on to the responsible department. I've been with TMo since 2004 and I still think these guys are the best.
Hello everyone, I was on the phone with TMHI support this morning to ask if the 1.2.74 firmware could be pushed to my Sagemcom gateway. I experience a WAN002 error every 1-2 weeks that causes me to power cycle the gateway to get internet back so I was hoping that this firmware fixes that issue. The TMHI expert was very nice and helped me through all the diagnostic procedures to figure out my problem. Ultimately, she was able to ask her supervisor to push the update to my gateway.
Although I cannot say for certain that it addressed my periodic WAN002 error, I can say that upon turning WiFi calling on, it stayed on and I was able to test it on a phone call and it remained on throughout. Only time will tell if it fixed the WiFi calling issue once and for all but I am happy to report that it looks hopeful that the issue has been addressed.
I have the same issue with Wi-Fi Calling and the Sagemcom gateway. I called TMHI support and the expert acknowledged that there was a problem with this gateway and Wi-Fi Calling. Regardless of how you connect to the gateway (its own wireless SSIDs or your own router), Wi-Fi Calling does not work. Suggestion for immediate workaround is to turn off Wi-Fi Calling until T-Mobile releases an updated firmware fix for this gateway. No ETA was provided.
Not sure if this helps those who have weak T-Mobile signal in most areas of their home but at least there is an acknowledgment of the problem with a promise that a solution is pending.
This is my 2nd time subscribing to TMHI and can confirm that Wi-Fi Calling did work the 1st time with the Nokia gateway.
Thanks for your update. Much appreciated. Glad you got a straight answer. Your input appears to confirm that it’s a firmware issue. Hopefully they’ll get it fixed soon. For those of us with phones on TMO, it should be less of a problem since if the Gateway has a good signal, so should our phones. Nevertheless, it should work.
After spending half the day with the Sagemcom gateway 1.2.74 firmware and making several phone calls with WiFi calling enabled across multiple phones in my household, I can comfortably say that my WiFi calling issue has been resolved.

I am having this issue quite frequently and drop calls constantly with the t-mobile gateway router -- every day multiple times per day when I’m within our home. Wifi calling is enabled on my phone, but appears to not functioning with our t-mobile internet. Texting is also an issue when on wifi. I have Verizon cellular service (rural midwest) and an iPhone 14 Max Pro. Everything works perfectly outside the 4 walls of our home. Oddly, other family members have Verizon service as well and seem to not be having the same issue.
Happy to know it’s not just me but frustrated to hear it’s an ongoing issue with seemingly no fix. We may just have to cancel our t-mobile internet service (which is sad as it has been performing perfectly for us in all other ways).
So like most everyone else I’ve just been living with wifi calling disabled using the Sagemcom gateway, but seeing some hope show up here is amazing. If I factory reset my gateway and then let it do its normal set up any chance that would trigger the firmware upgrade? Trying to avoid calling in and spending that much time on the phone to get it updated but checking now I’m still on 1.1.52
