These are replies to INVITE requests, but if you see them, the INVITE passed through the server as well.
If you are not aware of a firewall, then perhaps you don't have one unless is a default installation with it enabled or one on the network.
I suggest you do sip tracing on the client machine to see if the invite requests leave to the proper IP.
Ultimately can be also a problem caused by a NAT router with ALG, if the client is behind such device.

If we call with different DNS that is working fine then we see INVITE option like

Hello,
OPTIONS is not the request for initiating the calls, that is INVITE. You would need to know SIP a bit in order to be able to understand and configure Kamailio.
If you don't see any INVITE on kamailo server via ngrep when you call, then the issue is on client side or there is a firewall dropping it.
Cheers, Daniel
