Have u verified "attach accept" message which carries "EPS network feature support" IE ? This IE is used to inform UE about supported features at the network. Fist bit of third octet inform UE whether IMS VoPS is supported or not.
Hope, It may help you out.

LTE: Can a UE send Attach Request with IMSI if already Emergency attached with IMEI?

I have a question regarding the behavior of UE when SIMless attached. In case when a UE is Emergency Attached wth IMEI, can it trigger again Attach with IMSI, without been detached in the meanwhile?
