Same results when used UDP transport on caller and callee legs. And when `set_body_multipart` is applied at start of `request_route` block ``` /* Main SIP request routing logic * - processing of any incoming SIP request starts with this route * - note: this is the same as route { ... } */ request_route { if (is_method("INVITE")) { set_body_multipart("test", "text/plain", "delimiter"); msg_apply_changes(); # # $var(b) = "7e Od 04 55 75 69 20 4d 61 6b 65 43 61 6c 6c"; # # append_body_part("$var(b)", "application/vnd.cirpack.isdn-ext", "signal;handling=required"); }
# per request initial checks route(REQINIT); ```
