You can use uac.so module to hide from header information and you can even change it with your Kamailio IP address.

The config is like:
uac_replace_from("sip:$fU at your_domain")

Subject: [SR-Users] Change FROM to hide topology

Hi guys,

We have SIP Server > Kamailio > webrtc client. The only call flow we have is SIP server calling kamailio tha sends the call to webrtc client. We set up TOPOH to hide the sip server info but once the sip server initiates the call we still have the FROM details identifying SIP Server IP address.

We couldn't find a way to mask this ip using TOPOH. What would be the best way to hide the sip server IP address in this case?

Thanks a lot!
