AT&T getting ready to launch Voice-over-LTE
To date, MetroPCS is the only carrier in the US to deploy VoLTE. The somewhat slow adoption rate was not so much a question of “if” it would work, it has been about ensuring it would work correctly, and efficiently.
Obviously, equipment needs to support VoLTE, and the first generations of gear that MetroPCS sold that supported it, suffered very swift battery drain. Part of that was the youth of the LTE network, but also because of the equipment which had to handle separate antennas and chipsets to use it right. That meant a greater demand for power.
The AT&T VoLTE launch is said to be planned for May 23rd in Chicago and Minneapolis. As you might have guessed, your equipment needs to be compatible to use this technology, and right now, the only device (that we know of) that will handle it on AT&T is the upcoming ASUS PadFone X.
The PadFone X will handle LTE-Advanced and is also equipped to support HD voice using VoLTE. We have known about the PadFone X for quite a while now. AT&T and ASUS have been teasing the smartphone-tablet combo, but no release date has been forthcoming. Since AT&T already has LTE-A up and running in Chicago, and if the May 23rd date is accurate, then maybe we will see announcements for network enhancements same in Minneapolis, maybe some additional markets, along with a commercial launch of the ASUS PadFone X.

I wonder if ATT is soon going to announce VoLTE support for the Galaxy S5. The Asus PadFone is such a narrow niche and not even shipping yet. Doesn't make sense for the PadFone to the ATT VoLTE launch device.

The current S5 doesn't have the hardware built in to support VoLTE. Most likely a new version of the phone will be released in the fall that supports it.

Lame. I thought I read the S5 was going to support VoLTE. I guess it doesn't make much of a difference as VoLTE/HD Voice will only work on-network, right?

"Folks, and fine chumps, err, people at the FCC, we need MOAR bandwidth. We have to cap and throttle current customers because demand exceeds supply. Oh, and stop by because we are going to offload our voice calls onto our speedy LTE network to save us time and money operating multiple standards" - Randall Stephenson, CEO of AT&T.

To Randall Stephenson,
What AT&T's got speedy LTE? Where? *looks around*

"Voice-over-LTE, also known as VoLTE, is basically a Voice-over-IP (VoIP), except instead of using a regular circuit-switched method to carry the call (as is done currently on the 2G and 3G networks), the voice calls will be handled on the LTE network."
Voice calls on cell phones haven't been circuit switched since like forever.

I thought 2G and 3G voice was circuit switched.
Network switching subsystem (NSS) (or GSM core network) is the component of a GSM system that carries out call switching and mobility management functions for mobile phones roaming on the network of base stations. It is owned and deployed by mobile phone operators and allows mobile devices to communicate with each other and telephones in the wider public switched telephone network (PSTN). The architecture contains specific features and functions which are needed because the phones are not fixed in one location.
The NSS originally consisted of the circuit-switched core network, used for traditional GSM services such as voice calls, SMS, and circuit switched data calls. It was extended with an overlay architecture to provide packet-switched data services known as the GPRS core network. This allows mobile phones to have access to services such as WAP, MMS, and the Internet.
