At times WiFi calling and sending SMS doesn't work?

Any reason why you zipped it? By zipping it, I have to download it, unzip it, then run Wireshark with the extracted file. If you just attach the capture file, it opens Wireshark directly.
Sorry but the forum does not allow me to upload it without zipping it first.

I had no problem doing that. Take a look at my post.

I'll see about getting
.capadded to the allowed list of prefixes.Actually, looking at it, it is probably easier to rename the file to .pcap than to zip it.

Yeah, it's a bit strange the pfSense forum won't accept files created by pfSense packet capture.

so you can see answers there but not when doesnt work... So now sniff on the WAN it doesn't work... Do you see answers? Do you see it sending to that 141.207.229.233 IP?

FYI: .cap files now allowed in file uploads.

Below is capture of WAN port when it does not work. I let it sit for some time and on the phone it just shows calling but nothing is happening.
packetcapture (7).capHere's the capture of about 5+ minutes later when it works.
packetcapture (8).capTo me both captures look similar?

Was this problem ever solved?
I have a Galaxy S8+ and SG-3100 pfSense Security Gateway Appliance.
New install and having the same issue. -
No, it was not. You will never get confirmation from Netgate that anything is wrong but I'm using pfSense for years (6+) with WiFi calling and never had issues. One of last few (maybe more) updates broke it. Most likely introduction of Automatic outbound NAT rule generation.
(IPsec passthrough included) is just my guess.
I found other posts here and other places mentioning the same problem:
https://forum.netgate.com/topic/142370/wifi-calling-being-blocked
https://www.reddit.com/r/PFSENSE/comments/c7ze1s/at_times_wifi_calling_and_sending_sms_doesnt_work/
https://www.reddit.com/r/PFSENSE/comments/bkgj0t/issue_with_pfsense_ipv6_and_sms/emk3vvc/I solved it by turning OFF Automatic outbound NAT rule generation.
(IPsec passthrough included) and switched to Manual Outbound NAT rule generation.
(AON - Advanced Outbound NAT) and manually mapped 4500 port. So far for the past 2 weeks I have not had any failed SMS or phone calls while on the WiFi. It defiantly did the trick in my case. Hope it helps someone!

That is nothing new.
If they changed something to require static outbound NAT for NAT-T (UDP/4500) then they essentially broke the whole point of NAT-T.
This is not pfSense's fault. This is your Wi-Fi calling provider's fault.

NAT-T (UDP/4500
I agree that this issue might have something to do with Verizon but I also think if this would be a wide spread issue with other off the shelf routers than internet searches would be filled with it but somehow this only affects pfSense from what I was able to come across.

@JohnnyBeGood It's just NAT. If they did something stupid to require static source port 4500, the knob is there for you to turn. That will break if multiple phones try to connect to the same IPsec endpoint.
These are my states to AT&T. NAT-T doing what NAT-T does:
