Ah.

https://en.wikipedia.org/wiki/LTE_(telecommunication)

In telecommunications, long-term evolution (LTE) is a standard for 
wireless broadband communication for mobile devices and data terminals 
based on the GSM/EDGE and UMTS/HSPA standards. It improves on those 
standards' capacity and speed by using a different radio interface and 
core network improvements.[1][2] LTE is the upgrade path for carriers 
with both GSM/UMTS networks and CDMA2000 networks. Because LTE 
frequencies and bands differ from country to country, only multi-band 
phones can use LTE in all countries where it is supported.

...

Overview

LTE stands for Long-Term Evolution[7] and is a registered trademark 
owned by ETSI (European Telecommunications Standards Institute) for the 
wireless data communications technology and a development of the 
GSM/UMTS standards. However, other nations and companies do play an 
active role in the LTE project. The goal of LTE was to increase the 
capacity and speed of wireless data networks using new DSP (digital 
signal processing) techniques and modulations that were developed around 
the turn of the millennium. A further goal was the redesign and 
simplification of the network architecture to an IP-based system with 
significantly reduced transfer latency compared with the 3G 
architecture. The LTE wireless interface is incompatible with 2G and 3G 
networks, so that it must be operated on a separate radio spectrum.


So it it is IP based.

...

Voice calls

The LTE standard supports only packet switching with its all-IP network. 
Voice calls in GSM, UMTS and CDMA2000 are circuit switched, so with the 
adoption of LTE, carriers will have to re-engineer their voice call 
network.[106] Four different approaches sprang up:

Voice over LTE (VoLTE)
Circuit-switched fallback (CSFB)
Simultaneous voice and LTE (SVLTE)
Single Radio Voice Call Continuity (SRVCC)




I have not read it all, so I don't know how they interconnect with the 
landline network that supposedly has migrated or is migrating from PSTN 
to VoIP. I don't know if this is explained in the article or another 
article.
