5G Registration using iPhone is not successful

I am trying to Attach an Iphone over free5gc. As it can be seen from attached pcap, InitalContextSetup Request sent from AMF is getting rejected by UE.

Did anyone succeed attaching iphone over free5gc? If yes, please share the configurations.

Hi,@aleemgsl
The core network settings can be found in this link.
Also if you are using cellphone as UE you need to set the value of imsVoPS in free5gc/config/amfcfg.ymal to 1.
Also here is the hardware we have tested so far.
From TS 125.413

I think this part of the problem is caused by the settings of RAN and UE.
