Verizon and AT&T to offer VoLTE Interoperability for 2015

Verizon and AT&T to offer VoLTE Interoperability for 2015
Fans of the movie Ghostbusters will remember that the ghost fighters were not allowed to cross the streams of light that emanated from their proton packs. Don't cross the stream. That can be the slogan for VoLTE. Sure, it is great to make calls over a 4G LTE pipeline, but when you do, the streams don't cross. In other words, VoLTE calls do not cross networks. Which means that if the person you are trying to connect to uses another carrier than you do, you will have to revert to a regular voice connection.

But that is going to change next year as AT&T and Verizon plan on allowing VoLTE calls to cross over their networks. This way, a Verizon customer can have a VoLTE call with his good buddy who uses AT&T, and vice versa. This should be ready sometime in 2015

What are the other carriers doing in this area? Well, as T-Mobile CEO John Legere tweeted in his inimitable style, his network has already been testing cross-carrier VoLTE and HD Voice. Eventually, customers of all four major U.S. carriers will be able to talk to each other using a VoLTE network.

Looks like the duopoly is putting the hammer down on T-Mobile and Sprint.

As long as ATT and VZW don't try to use VoLTE 'interoperability' to squeeze the other carriers, interoperability is a good thing. The more the merrier.

Actually not. When the other end is not VoLTE, the one end connection is still over LTE, but the HD quality is lost at the other end with a regular connection.

This is a good thing. Have been hearing that the current Verizon phones that can use VoLTE couldn't talk n surf at the same time unless talking to another Verizon person with VoLTE too. Upgrading the voice technology has its pros n cons. You can use less voice hardware, but it comes at a price.
