Is there a way to ensure that the source IP address from witch the SIP user register is not tampred with , is there a feild in the SIP register message  header can be used to achive this security ?

i have an asterisk server in witch SIP users register through an SBC(session border controller) , i wanna make sure that those users are really registering from the IP they are claimming they are registering from and that the source IP not changed in the middle of the path 

                                                                                   
|SIP client|-----------|internet|-----------|SBC|----------|asterisk|
