Dialer won't allow SIP calls (claims "call barring" is on)

I'm trying to use the Nexus 6P's native dialer to make calls through my SIP provider. I have a configuration that works perfectly on the Nexus 5X and older 6 (shamu). I entered all my information in Dialer > Calls > Calling accounts > SIP accounts, and then enabled the account under ... > Calling accounts > All calling accounts. However, whenever I attempt to make a call through my SIP provider on the 6P, a message pops up saying "Can't make outgoing calls while call barring is on." Does anyone have an idea what might be causing this? Note that:
I can make regular phone calls from my mobile number just fine, tested with both a Verizon and a T-mobile SIM. However, the SIP call barring problem persists regardless of which SIM is in the phone.
I can make SIP calls using other apps, like CSIPSimple, so it's not a port blocking issue.
I can receive incoming SIP calls (to my DID number) just fine when enabling ... > Calling accounts > Receiving incoming calls, so clearly I didn't mistype my SIP account password. (I visually checked that all the other settings are identical between my 5x and 6P.)
I'm definitely on WiFi when I experience the problem. To be extra sure, I even tried it with airplane mode and WiFi both on, which is fine for CSIPSimple or incoming calls but still doesn't work for outgoing calls with the android dialer.
The message pops up instantly, making it seem like a setting on the phone rather than a response to network messages.
For what it's worth, I'm running build MMB29M (android 6.0.1). My phone is unlocked but not rooted. (I can still get root access to /data by booting TWRP, but have never mounted my system partition read-write.) The one thing it might be is that I put a Verizon SIM in my Nexus 6P when first booting it, whereas my other phones were all first booted with a T-mobile SIM. I think that caused some VZW apps to be installed that I since removed; perhaps it messed up other settings. I'm a bit reluctant to wipe my phone and try again, but will do it if people think it's the only solution.
Thanks.

My 6P won't allow the SIP account. Gives me an error every time I try to set it up.

Do you have Verizon, or a different carrier?

I experience the same problem on a Nexus 5X with Android 6.0.1 SIP calls only exhibit this problem when the SIP username looks like a 10 digit phone number. All other outgoing SIP calls work correctly.

I am having this same exact issue on a Nexus 5X using Cricket. Anyone come up with a solution?

SOLVED
Okay, I finally broke down and wiped my Nexus 6p, flashing the latest google ROM with fastboot -w. This time I booted it with a T-mobile SIM for the first time. Lo and behold, outgoing SIP calls started working again.
This is super nasty behavior, because merely switching the SIM and even reflashing without -w did not solve the problem. The mere act of having a Verizon SIM in your phone the first time you boot it ends up crippling the SIP feature. On the plus side, it will probably continue to work even if I pop the Verizon SIM back in.
So now I'm going to lose an hour redoing all my settings on my wiped phone, but I'm super happy to have SIP working again.

No VOLTE and no WiFi calling T-Mobile, what gives?

I'm gonna make a post here since NOTHING seems to be working. I'm a T-Mobile customer. Yesterday, I purchased a great condition nexus 6P from someone because my LG G5 is cracked and I was getting tired of it anyway so I opted to just buy a nexus instead of using my insurance on that phone. Everything is all good except for one major issue. VOLTE and WiFi calling just refuse to work with my sim in the Nexus.
I've called T-Mobile twice. I've factory reset from back up and reset settings twice. I've hard reset from stock recovery once. I've wiped network settings and restored default apns. I've manually changed the apns from what I see on Google, reddit and here. I've copied my apns from my LG G5 where VOLTE and wifi calling work perfectly fine. I've cleared cache. I've cleared the cache of the project fi and hangouts apps just in case there's something left over from the previous owner. I've gone into the *#*#4636 menu and tried a bunch of different stuff several times but no matter what I absolutely can not get wifi calling or VOLTE to work with TMobile on my nexus 6P. LTE it's self works perfectly fine for data.
Yes, all settings for wifi calling and enhanced LTE calling and VOLTE are turned on lol. I've tried the trick where you toggle wifi preferred on and off and restart the phone. Nothing happens. I don't even get a wifi calling reg error. It never shows as active in the data toggle in the quick settings are nor the status bar or dialer. It just isn't active. Same for VOLTE. I AM getting band 12. I can see it in the LTE discovery app. VOLTE just isn't working though. Whenever I make a call I can see LTE switching off and it switches to HSPA therefore making calls really difficult in my shoddy signal area at my house which is why I really need it to work.
I'm fairly certain I can root and install a ROM which will fix these problems but I don't own a PC. . I thought MAYBE the previous owner had previously had the phone rooted and tinkered with something somewhere that may have messed something up but that doesn't appear to be the case. Bootloader is locked and recovery is stock.
Can anybody help and tell me what in the world is going on here? I don't want to have to sell this nexus and revert back to my cracked screen G5. I would just switch carriers but I still owe money on the G5 so I was just gonna ride it out til I payed it off.
O and one last thing, after scowling google and forums for hours on end yesterday and today I did see one post mentioning something about this stuff being related to IMS provisioning and settings which are tied to a phones IMEI on T-Mobile and not the sim card and how that person simply called T-Mobile and got a hold of wifi calling technical support who was clueless but created a ticket for him and within 72 hours the issue was resolved. OK well I did the same exact thing and they refuse to create a ticket for me because it's not a T-Mobile phone and because according to them they are not allowed to create a ticket because wifi calling works fine in my G5 and therefore it's the phone and not them or their network lol. What a crock. I'm willing to bet if I put the sim in another unlocked phone with 7.1.1 and wifi calling fully available that it isn't going to work either. There's some sort of communication error going on between the sim being in this phone and their network it appears.
Check these screenshots out. T-Mobile is clueless

I can only suggest;
1) Find a PC and re-flash the latest factory images from Google. Both "fastboot flashing unlock" and "fastboot flashing lock" will wipe all data, so backup first. Also confirm it fully boots correctly after flashing before you re-lock the bootloader.
2) Get a new 3-in-1 SIMM from T-Mobile. You can use their web site to switch cards and give it 24 hours to be fully provisioned.
3) Confirm your E911 address is correct on T-Mobile's site and wait 24 hours after any changes for Wi-Fi calling to actually start working.

I HAVE THE SAME EXACT PROBLEM AS YOU POSTED!!! GONE THRU THE SAME PAIN. LOL I'll attempt the ticket thing to see if I get anywhere. Did you ever get it resolved?
EDIT:
My theory is that since the phone was used in Project FI, they specifically turn off this feature in the back end for the specific phones, by Imei or something since project FI uses T-Mobile as well.
EDIT 2:
they wont' create a ticket for me either. I guess I will just have to ride it out.
EDIT 3: I FIXED IT!! NEXUS 6P VOLTE AND WI-FI CALLING FIX T-MOBILE
I flashed back to android 6.0 Build#: MMB29N (I used the Nexus ToolKit 2.1.9: google it. BTW, your phone will be wiped, so backup first) VOLTE just started working with this version of android 6.0. Then I upgraded using the OTAs and now i'm on 7.1.1 build#: N4F260 with VOLTE and Wifi calling working as it should! I hope this helps someone out there!

For what it's worth, reverting to the build you mentioned fixed it for me on my two Nexus phones coming from Project Fi to T-Mobile as well! Thanks for the help!

You only need to install the radio from build MMB29N. I did this by downloading the build from the android website. Extract the radio from the zip and install it (I used nexus root toolkit but you can also just use flashboot if you wanted). This means you don't even need to revert your image and lose your data.

wish I had seen this sooner. cheers!

Had the exact same issue and this fix worked for me. Wasted a couple of hours with T-mobile (they were actually very helpful and debugged everything on their end to confirm the provisioning was good) and then 2+ hours with Google support. Actually had already filed for a device replacement which I canceled after finding this post.

I'm so glad I found this thread - my VoLTE and WiFi calling has not been working on T-Mobile and I'm anxious to give this a try. Numerous phone calls and support tickets with T-Mobile haven't resolved the issue. I don't know much other than how to follow detailed directions. My phone isn't rooted and bootloader is locked. I'm on Android version 7.1.2. Is there a way for me to install the MMB29N radio on my Nexus 6P without losing my app data given that my bootloader is locked?

Flashing the radio -sadly- requires an unlocked bootloader.

Did you resolve your problem?
In android 7.1.2 did you notice in Set preferred network type is set at " LTE/GSM/CDMA auto (PRL) "? 7.1.2 has been giving me issues with sms/mms. I noticed Android 6.0 has this set to correct T-mobile bands.

All works for me in 7.1.2. Make sure you don't download the Verizon version of the stock ROM. That was my issue why I couldn't have volte and Wi-Fi calling

No cellular signal, Radio won't turn on.. Please Help

I just bought a used 6P.
I am having an issue with not being able to pickup a cellular signal. When I place my SIM card in the phone and have voicemails it gives me the notification but I don't have any signal.
I took a recording of some troubleshooting.
And the sim card works fine in my 5x.

You might want to contact your cell phone company and let them know you switched phones. They might need to do something on their end so the sim will work with your new phone.

Thanks for the suggestion but when I swap my SIM into any other phone I have it works fine and picks up a signal without an issue.
Anyone else have any other suggestions that I can try. Got the phone for a good price and I was hoping to resolve this signal issue.
I even tried flashing custom Roms, and vendor and radio's nothing seems to work. I've ensured my APN settings are correct as well.
I hoping it's not hardware (antenna).
I don't know what else to try.

Model is: H1511
NA Version
I'm in the US
I have Straight Talk running off of AT&T towers.
No issues with my service or SIM at all. I have another 6p and a 5x that my sim works fine in.
I actually just looked up the warranty status on the 6p and found that it's in warranty until August! Looks like if it turns out to be a hardware issue I'll be sending it to Huawei

Just read the fine print and it states the warranty is only valid for the original purchaser with a proof of purchase

I was having a similar issue yesterday too. H1511 from VZW to Tmobile. No data but could receive calls. I ended up installing one of the custom roms (Pure Nexus or Resurrection Remix, both worked for me ) along with a vendor update (N4F26J_vendor.img) and am now getting signal/data.

Thanks I did flash a custom ROM and vendor update to test but it was a different vendor. I flashed Chroma ROM and I believe the vendor file was MCT40 (something close to that). I'm not home right now to check but maybe I'll try flashing one of the Roms that worked for you along with the same Vendor file.
I'll let you know how it goes.

Cool! Good luck to you. Not sure if you have tired yet, but you might just trying getting VZW to switch out your sim.
------------------------------------------------------------------------------------------------------------------------------------------------------
I have been using the Resurrection Remix rom for the past day or so.
Pros:It is nice, lots of customization. Cons: Some settings will not stick or have bugs. Voice unlock being the primary one. Another setting (vibration related?) was actually located in two places.
I used Pure Nexus for about a hour and thought, well I wanna see what Resurrection Remix has to offer and jumped ship.
Pure Nexus, as the name implies, seems a lot cleaner the boot animation is pretty close to the stock one. And everything I tired, just worked.
*YMWV as review period was short and this model is a second hand unit. Additionally, I am not an expert!

Thanks but I don't have Verizon. I use straight talk with an AT&T sim.
The newer radio/vendor images didn't work for me, flashed a new ROM as well. Still no go. The menu looks different but it still won't give me a signal or turn the cellular radio on.
It recognizes my SIM and tells me I have voicemails but still can't make or receive calls, no mobile data, etc... Popped the sim back in my 5x and it works fine.
Not sure what to do at this point.
Might just set the phone back up to stock and sell on eBay as is. I wish I could've gotten it to work though.

All good.
It's not the SIM, SIM works fine in any other phone. I have 4 other phones I've tested it in.
If I was to try and switch it out I would have to buy a new SIM from Straight Talk.

#*#*4636*#*# Info Menu phone number discrepancy

Hey all, I've Googled this all afternoon and I can't find a good, or even an answer, really. I've been having a few issues with my 6P dropping cell connection. I'm trying different radios (anyone use the Huawei engineering radio?), and the phone currently runs Lineage OS 14.1, just flashed the May 8 nightly. Also running the current Franco kernel and latest TWRP. My carrier is Project Fi (which I love, even in a rural area). I love the phone and had had zero problems until I updated to the latest radio (3.81) a week or so ago and then I started getting random dropped connections. I was on Pure Nexus then and since switched to Lineage primarily for the consistent updates, but when it's connected the service is the same on both ROMs.
That brings me to my question. I'm in the Info Menu looking at various settings and I notice that the phone number listed there isn't mine. In fact it's an area code in a different state. My question is if this is a Fi thing or if it might be the cause of my connection problems (and how does that number get changed in the first place? I haven't been diving very deep on this phone). The phone was an RMA and has a build date of Nov '16, wasn't activated before. I recently moved from Ting to Fi, can't imagine that's the issue. Anyway, anyone else have this problem, if it is a problem? I've never seen a different number in that menu, so I'm curious.
Also, anyone else having problems with the 3.81 radio, or use the Huawei engineering radio?

Have you factory reset with stock software? Maybe Fi is trying to do something with the carrier switching. I've been trying to find the engineering radio for a while,. But all links I find are outdated and no longer work.

I'm thinking it's a problem with Lineage as I had zero issues on stock or on Pure. I have an engineering radio image but no idea how old it is, though if it fixes the problem old is fine.

Care to share that engineering radio?

I've been having that issue with all the roms I've been trying. Once I lose lte I lose it for good. I have to stick to roms that have the option to change apns or I won't b able to use data at all

This is a Google Fi thing and is normal. The number is likely T-Mobile, although you should actually have 3 (one for each carrier). Google Fi works like Google Voice and forwards calls to these temp numbers. As for the radio, I would downgrade to 3.72 as this is a known issue on T-Mobile.

G935V on Android N 7.0 issues with receiving calls/texts [Total Wireless]

I have been going through a weird issue on Total Wireless. When I use Android 6.0.1 and below, I have no issues with my service at all, everything works as it should. The issue comes into play when I use any Android 7.0 ROM, be it official or custom. Outgoing calls/4G data are fine, but I cannot receive any phone calls or send/receive texts. The only way for me to be able to receive calls and send/receive texts is to dial out once. After this, everything works as it should, that is until I reboot. Then I it goes back to the partial working state until I dial out again.
The issue persists whether I am using CDMA/LTE or Global Network modes. I have tried every single possible combination of starting with a fully working 6.0.1 firmware and upgrading through Smartswitch, with and without a full Wipe performed afterwards, doing a full 7.0 firmware flash. The issue is always present, and I am not sure if TW has issues with Android 7.0 or if there is a problem with my account. Their CS is absolutely useless in helping me with the issue, and our chats always end with if I can make a phone call, then the issue is resolved. They don't understand that the issue is still present, but it only crops up after a reboot of my device.
I have tried 3 different SIM cards and they have deleted and re-added/reprovisioned my device/number to their system but nothing seems to help this issue. APN is the usual TRACFONE.VZWENTP. It's really weird that it happens on two separate devices that I activate with my mobile number.
My only thought as to what it could be is maybe some weird provisioning error with the number coming from Verizon. Total Wireless doesn't have any type of VOLTE capabilities on their network, yet I was able to use a rooted Note 4 device and activate Advanced Calling/HD Voice and I believe Wifi calling as well and use it fine on their service. One oddity I noticed is that when the phone is in the initial 'Searching for Service' state on a fresh boot when I dial out while connected to Wifi, sometimes I will see Mobile Network Type change to IWLAN, whereas it usually says LTE. After dialing everything works correctly.
Any ideas on further troubleshooting steps I can take? If nothing can be done, maybe there is some way I can have a boot up script that makes a ghost phone call to any random number and immediately disconnects so I don't have to remember to dial out whenever I reboot my device?
Thanks

I don't have a solution yet, but you're not alone. I have a stock G935V (running Nougat) with Tracfone service running over Verizon's network. Whenever I start up the phone, the phone will indefinitely remain in a "Searching for Service" status until I initiate one phone call. Then the network instantly switches to "Verizon Wireless" and everything works correctly for as long as the phone remains on.
A long phone call with Tracfone and Verizon yielded no solution: They indicated everything is configured correctly in my account. Various replacement SIM cards didn't change anything either.
This issue happens with both stock Samsung S6 phones and the Samsung S7 phone in my household. All are running Nougat.

Any update here? My girlfriend's phone has the same issue since moving from Verizon to StraightTalk.

Tracfone tried, half-heartedly, to solve the problem by sending me 3 different sim cards. The problem never went away. I just got in the habit of initiating a call to voicemail whenever I restarted my phone.
The problem went away when I upgraded my S7 Edge to Android v8 Oreo.

I have flashed the Nougat "U" firmware on my Verizon S7 Edge. I had VoLTE, hotspot, HD voice when calling someone on Verizon (but the HD symbol doesn't show on my dialer, only on theirs).
Only issue was that. when I introduced the TW SIM, the APN was auto set for Tracfone (and it wasn't working), so I had to manually change it to the TotalWireless one.
Since then I had received the Oreo upgrade and the following security update... and it's still OK.
