Did you know that your voice calls still go over the older school 4G LTE network while your data is on the 5G one? Yes, just like in the last days of 3G the Voice over LTE (VoLTE) handoff was a rarity, now the so-called Voice over New Radio (VoNA) technology over 5G is just about to be implemented, even though we’ve had 5G data networks for a good while.
It’s the same as what happened with LTE. With LTE we rolled out data first, then later VoLTE… To have a good, strong reliable voice service on 5G you need a big, strong 5G footprint.
It’s important to work out any kinks because once a call is set up on 5G it’s undesirable for it to get bumped down to LTE. Every time those changes happen you can have potential problems.
We’ve been driving very hard with the vendor community. We’re getting close, but we’re not ready. We don’t yet see the quality in software and vendor products.
