Subject: [SR-Users] Kamailio PCSCF route logic
Hello community,
We made some modifications to Kamailio PCSCF sample cfg file, so when PCSCF receiving an tcp SUBSCRIBE message it add ;transport=tcp to the end of Contact URI. Below is what we added the route
block right after if (is_method("INVITE|SUBSCRIBE”)) logic
if (is_method("SUBSCRIBE") && proto=='tcp') {
$var(original_contact_header) = $ct;
$var(new_contact_header) = $(var(original_contact_header){re.subst,/(.*:.*)(>);/\1;transport=tcp>/g});
remove_hf("Contact");
append_hf("Contact: $var(new_contact_header)\r\n");
msg_apply_changes();
}
We did see the ;transport=tcp been added but we also seeing a bad line ;alias=[…] is added before the To: line
Does anyone know what function might cause this ;alias been added before To: line?
BR,
Weiqi
