Is this a NAT issue? 

The network is like this： 

alice--192.168.199.214     company ip--116.228.89.198    kamailio IMS(cloud
server)--120.76.118.128 
bob--192.168.199.124 

I can see INVITE was sent from 116.228.89.198(company ip) to 
120.76.118.128(kamailio IMS), then 120.76.118.128(kamailio IMS) reply a 100
trying to 116.228.89.198(company ip), after that 120.76.118.128(kamailio
IMS) sent INVITE to 192.168.199.124(private ip of bob), because 
192.168.199.124 is a local ip address, I guess kamailio IMS in the public ip
address can't find a route to this address. 
So, bob did not receive this INVITE message from alice. 

Is my analysis right? What should I do to let the IMS run properly?
