That'd make sense, I seem to remember reading that ATL was one of the test markets, and the 18.0 update likely had it enabled within the test markets.
Thanks.

If you have a Chicago area code, it did work under 18.0, as did carrier aggregation. I think 18.1 has enabled both for all users, and not just home market area codes.
i updated to 18.1 in SF Bay Area. no real change in LTE speed (as suggested by our Stockton poster) , and from what i gather VoLTE is not active here yet (i tried dialing 611 for kicks and it went to 4G)
i was hoping (very slim hope) 18.1 might have fixed a few things which leads to the iPhone 6 having worse signal strength than my old iPhone 5 since i have heard other claim that on Verizon, at least, the iPhone 6 has better signal strength/stability than the iPhone 5 and 5S.
but as i guess that was a bit of wishful thinking...

Mine was doing that until today. Verizon and on 18.0. Have VoLTE enabled and its working. (you can tell a definite difference in the sound when on VoLTE call) But this evening I have the wifi icon always instead even when on VoLTE call. It would have wifi and when a call came in switch to LTE and the whole time on a call the display showed LTE. Once disconnect wifi would come back. Now wifi icon stays there even during a call. No idea what changed. Well I just had a thought, I updated both phones to 8.1.1 yesterday. Was on 8.1. But I could swear this morning I saw LTE while on a phone call. Wife's phone same thing and also updated yesterday.
So, if I see my phone switch from LTE to 4G at the start of a call I do not have VoLTE working yet? I have updated to 18.1. My brother near-by sees his phone stay on LTE. Maybe it's my area but could be my phone. The coverage map shows me solidly in a covered area.
The coverage map doesn't seem to show volte active in the Boston area... but my phone stays on LTE after updating the carrier settings... so unsure what's going on there.
Anyone else experiencing decreased battery life? I've been putting off this update because of this possibility.
That's sounds correct. It should stay on LTE. However you will know if you are on a VoLTE call. Its unmistakably different than a regular call. You must both be on LTE before the call is connected though. On Verizon a call would come in and if on wifi the LTE symbol would appear and wifi would go away. Then come back after the call was over. It seems that after 8.1.1 the wifi symbol stays on the display during a call. Not sure if ATT changes now or not.
Did some testing on AT&T for my area and have not seen any speed update at all. Then again, it could just be my location.
Both parties have to be on LTE and have VoLTE enabled device for the VoLTE to work. A regular call to any other number will go over the cellular network.
Don't really need it for VoLTE. That has been on since the iPhone 6 was released on Verizion. Just have to enable it.
No, both parties don't need a VoLTE enabled device for it to work. It will work to any number, any time, on any type of network - landline, VOIP, satellite phone, call to North Korea, et al - VoLTE on the receiving end is not, and never has been, a requirement. All that VoLTE is, is the initiation of a call over a packet-switched data connection instead of a circuit-switched phone connection - optimized specifically for LTE as a standard VOIP connection uses far more bandwidth.
Careful. VoLTE is not HDVoice. You need to be using VoLTE in order to have an HDVoice call. VoLTE is the fact that your voice is being transmitted as data over the LTE connection.
If both parties are using VoLTE and they are on the same carrier (for now), their voice can be carried using a higher data rate and thus use a better codec, which the carriers are calling HDVoice.
Just did the upgrade on my 6. Went to General>about and it gave me the option to update. Now on 18.1.
AT&T completely disagrees with you, and they do have more knowledge of their networks:
http://www.att.com/shop/wireless/services/hd-voice.html
To use AT&T HD Voice, both caller and receiver need an AT&T HD Voice-capable phone and must be located in an AT&T HD Voice coverage area
as well as the FAQ tab reiterates this numerous times. As AT&T calls VoLTE on their networks HD Voice, your post is wrong for AT&T and the context of this thread about the carrier update.

Based on the questions within this thread, meaning the default usage of the majority of AT&T customers, this carrier update would only affect their use of HD Voice and the built in iPhone phone app. Sure the theoretical discussion of VoLTE and the distinction vs AT&Ts implementation of HD Voice is a nice technical discussion, but the impression given by the poster that all iPhone calls will benefit due to the carrier update isn't correct and confusing to those posting most of the questions in this thread:
There are numerous 3rd party VoIP iPhone apps (the few I've tried are horrible) and I presume VoLTE apps that use data vs cellular connections, sounds like you may use some successfully, so it would help the discussion if you mention how you make VoLTE calls on AT&T - what apps, what limitations for destination caller's hardware, etc, which would help people reading the thread possibly improve their use of their phones, and what info you have that the carrier update would affect what you are using for 'true' VoLTE calls - would 3rd party apps sending voice over data get benefit from the carrier update or did they come up with their own voice to data conversion code-base - it isn't automatic that developers reference the same common code library that AT&T has on the phone or that AT&T would make it available to 3rd party apps. It is theoretically good practice for common code libraries but that might cut into AT&Ts control of their network and revenue, so perhaps 3rd party voice over data apps don't have access to the new code in AT&Ts carrier settings update.
Sounds like there's HD Voice/Calling, and then there's VoLTE, and then there's VoIP.

"I just talked to AT&T tech support and I was told that the 18.1 carrier update is an audio fix between VoLTE devices and non VoLTE devices. When a VoLTE call connected with a non VoLTE call their was "garble"."
For what it's worth...
