Verizon Says VoLTE to Launch in Coming Weeks
Verizon Wireless today announced the pending launch of its delayed VoLTE service. The service will go live in the coming weeks, and will allow select devices to connect HD Voice calls and Video Calls. Advanced Calling 1.0 uses Verizon's LTE 4G network and requires that both devices have LTE coverage. Callers will be able to see who among their Verizon Wireless contacts are available for HD Voice and Video Calling with simple icons in the contact application. Both participants need to be Verizon customers. HD Voice and VoLTE-backed Video Calling won't work if a Verizon customer calls someone who uses a competing network. The audio portion of Video Calls will be in high-definition, and calls can be switched from voice-only to video and back with ease. According to Verizon, VoLTE service will launch nationwide and arrive on compatible devices through a software update. Verizon didn't say which devices will be compatible, but HD Voice and Video Calling over VoLTE will be free to use. T-Mobile offers VoLTE-backed HD Voice over much of its LTE footprint. AT&T launched VoLTE in May in a handful of markets.
AT&T and Verizon Kick Off Interoperable VoLTE Calling
AT&T and Verizon Wireless have begun allowing some customers to place VoLTE calls to one another. The carriers' deployment of interoperable VoLTE is woefully behind schedule.

AT&T, Verizon Intercarrier VoLTE Launch Target Comes and Goes
AT&T and Verizon Wireless are still working to launch support for intercarrier VoLTE, despite missing the initial target. The companies expected to allow one another's customers to connect VoLTE calls between them before the end of 2015.
Good luck to them
I think CDMA works very, very well for voice. I had 1X far too often on my Verizon phone.
Sometimes HSPA+ works (on at&t) better in rural areas for data, and I have a feeling WCDMA(at&t)/CDMA(verizon) will work better for voice calls in rural areas too due to the channel sizes. No harm in having VoLTE but it'll be a long time before it will be as reliable as WCDMA/CDMA in many areas.
