Hi Experts.

Do you see operators using VoLTE only, not CSFB?

2

Yes, Jio.

Jio is.

Thanks.

I hear many UE has copmatibility problem with IMS.

In my network, Operator limit phone models for VoLTE.

5

Yes, because they don’t have 3G, so it is more about “limitation” rather than “choice”.

6

It was a choice for not going with Legacy NW :wink:

This is strange, as VoLTE look to be more stable these days compared to CSFB.

7

There was no legacy network to begin with, so in that respect it was only choice available. :wink:

I thought query was related to availability of such NW.

Apologies I missed the part where query was about VoLTE vs CSFB on the NW…
