Thank you for that reply, Joshua. Henning, we can restrict access using the firewall, but unfortunately that doesn't solve the problem with the address that's put in the SDP.

Re: [asterisk-users] Listen on 2 of 3 IP addresses
The answer is to use chan_pjsip since chan_sip is all but dead, unsupported and going away in v21. Instead of making chan_sip listen on all IPs then making a bunch of firewall/filtering rules that block one of them from being used, use chan_pjsip. It is the right solution as it is the supported driver and will continue to see updates and bugfixes. If you haven't started a migration from chan_sip to chan_pjsip yet, it is best advised to make a migration plan and do it now. If there is a case where something in chan_sip hasn't made it into chan_pjsip (or it did but hasn't been really touched/updated since) and you really need that functionality, now is the time to figure that out.
