Hello Experts.
After UE goes to SRVCC from LTE, is it possible it goes to VoLTE from 3G in retainability?

Hello All.

If a phone fall back from VoLTE to 3G, on return does it return to VoLTE or it falls back to 4G?

If you lost the 4G coverage during the VoLTE call, you will go SRVCC to 3G till end the call.

After that, fast return will be triggered to camp on 4G again.

A CS call can go to VoLTE, called rSRVCC. But it’s not used practically.
