What is SVLTE voice solution?

Hello Experts.

Did any one hear about a voice solution called SVLTE?

In theory it is a voice solution alternative to VoLTE.

But it needs an overlay coverage for 3G and 4G.

And dual radio connection.

Voice service run on 3G data on 4G.

I never heard a live deployment of this…

Usual ways for LTE voice are CSFB and VoLTE.

Yes. It has many limitations.

Voice on CS, Data on LTE.

Was used a little bit during CDMA days but doubt there are deployments after VoLTE became mainstream.
