找不到命令append_branch

Question

我是kamailio的新用户。我正在尝试使用fork.cfg将sip注册发送到%2目的地。我得到了以下错误，但我已经添加了装入模块tm.so，为什么我仍然得到这个错误？

我的脚本如下所示(默认脚本)：

mpath="/usr/lib/x86_64-linux-gnu/kamailio/modules"


loadmodule "sl.so"
loadmodule "tm.so"
.
.
.
.
route{
        # for testing purposes, simply okay all REGISTERs
        if (method=="REGISTER") {
                log("REGISTER");
                sl_send_reply("200", "ok");
                exit;
        };
        # try these two destinations first in parallel; the second
        # destination is targeted to sink port -- that will make ser
        # wait until timer hits
        seturi("sip:nobody@kamailio.org");
        append_branch("sip:parallel@kamailio.org");
        # if we do not get a positive reply, continue at reply_route[1]
        #t_on_failure("1");
        # forward the request to all destinations in destination set now
        t_relay();
}

我到底需要哪个模块才能让append_branch正常工作？

感谢您的帮助！

append_branch()函数曾经在核心中，但自从几个版本前以来，它被移到了corex模块：

• https://www.kamailio.org/docs/modules/stable/modules/corex.html#corex.f.append_branch

当您不知道函数(或其他配置元素)驻留在何处时，请查看kamailio.org维基中的字母索引：
