IOS 18 Voicemail feature

I am facing an Issue regarding the voicemail feature. when someone calls me, it would go to voicemail only if I click on the voicemail icon. If I do not respond at all to the incoming call, it does not give the caller an option to record voicemail. I have tried switching the voicemail on and off, its working on other devices Iphone 14 and 15 for my family member, just not for me. How can i resolve this?
