Disregard. It was my mistake. I had sp_key.pem in my kamailio config when it was actually sp-key.pem. Doh. Took me way too long to see my mistake but it is working now and adding the identity. Thanks for the help everyone!

Thanks for the replies. I think I am understanding it better now. My issue now is I am getting this error:

ERROR: {1 84911190 INVITE 9eea2bb8-aa08-123d-c0b5-5a8b7787aa29} secsipid [secsipid_mod.c:444]: ki_secsipid_add_identity_mode(): failed to get identity header body (-451)

-451 = SJWTRetErrFileRead which I assume is either the certificate or the private key. I am able to download the certificate using the URL so I guess the key? I have permissions on the key as 600 (-rw-------) and the user:group for it is kamailio.

It's still a self signed but I generated it with the TNAuthList, etc like a production certificate. I have stir/shaken working on s production machine but it uses libstirshaken and not secsipid.

this is what i do (i have a redirect server receive the INVITEs to be signed, I add the header and then do 302, the initiating server then add it to the INVITE and sends the invite out:

 if ($rm=="INVITE") {
$var(rc) = secsipid_add_identity("$(var(from){s.numeric})", "$(var(to){s.numeric})", "A", "", "https://pki.domain.com/stir-shaken-cert.pem", "/etc/kamailio/ec256-private.pem");

if ( $var(rc) > 0 ) {
msg_apply_changes();

update_stat("stirshaken_create_identity_failed","+1");
send_reply("503", "Service Unavailable - can not create Identity header");
exit;
}

append_to_reply("Identity: $hdr(Identity)\r\n");
}

hope that helps

Hmm you are correct. I took it out and it started fine. So what exactly would I need for our outbound stirshaken?

Just secsipid_add_identity?

I guess I've been looking at this for too long today. Just lines and lines after a while.

Except for `expire` and `timeout`, those parameters don’t exist for secsip id- at least according to the module documentation: https://kamailio.org/docs/modules/stable/modules/secsipid

Hi everyone. Wanting to see if someone could point me in the right direction. Still very knew to Kamailio but I am beginning to understand it better. I'm making an outbound proxy and have everything working well besides stir/shaken. I'm looking at the module page and have went back and forth with chatGPT and can't seem to figure this part out. I keep getting errors on the modparam lines. 

 

Obviously this is a self signed cert because I'm just testing. I am able to reach and download the cert from the Web server. 

 

Thank you for any assistance. 

 

# SECSIPID for Stir/Shaken 

modparam("secsipid", "private_key", "/etc/kamailio/secsipid/private.key") 

modparam("secsipid", "certificate", "/etc/kamailio/secsipid/cert.crt") 

modparam("secsipid", "authority_cert", "/etc/kamailio/secsipid/ca.crt")

modparam("secsipid", "expire", 600) modparam("secsipid", "timeout", 2)

 

route[STIRSHAKEN] {

    if (is_method("INVITE")) {

        if (!secsipid_add_identity("$fU", "$rU", "A", "", "http://myIPaddress.com/stir_shaken_cert.crt", "/etc/kamailio/secsipid/private.key")) {

            xlog("L_ERR", "Failed to sign call with ID: $ci - From: $fU\n");

            send_reply("500", "Internal Server Error");

            exit;

        } else {

            xlog("L_INFO", "Successfully signed call with ID: $ci - From: $fU\n");

        }

    }

 

    # Relay the call after signing

    route(RELAY);

}
