Calls in CSFB (even if VOLTE available) with IOS 18

Since the update to IOS 18, my device (Iphone 13 Pro Max) performs the Calls on 2G even if the VOLTE/VoWIFI services are enabled/available on my device/SIM/Network. To solve the issue it is required the Device Reboot.

After a deep analysis, it seems that Device with IOS 18 goes in wrong state in some scenarios (answers by the network??) and starting from that moment it does not open the APN IMS and performs all calls over 2G (if available).

Problems was not present on IOS 17.
