asterisk - 在星号服务器中调用期间引发的错误

Question

今天我的星号暂时无法接听电话。当我检查星号日志时，在此期间出现以下错误。

Purely numeric hostname (1002), and not a peer--rejecting!

在我重新启动星号后，问题解决了。问题是什么？

很可能这意味着您的 dns 服务器无法正常工作。使用本地 dns 缓存服务器或多于一个 dns 服务器。

其他可能的情况——你调用像 SIP/1234 这样的东西，它不在你的 sip.conf 中。

这是相关的源代码部分，它有描述：

peer = sip_find_peer(peername, NULL, TRUE, FINDPEERS, FALSE, 0);

    if (peer) {
            int res;
            if (newdialog) {
                    set_socket_transport(&dialog->socket, 0);
            }
            res = create_addr_from_peer(dialog, peer);
            dialog->relatedpeer = sip_ref_peer(peer, "create_addr: setting dialog's relatedpeer pointer");
            sip_unref_peer(peer, "create_addr: unref peer from sip_find_peer hashtab lookup");
            return res;
    } else if (ast_check_digits(peername)) {
            /* Although an IPv4 hostname *could* be represented as a 32-bit integer, it is uncommon and
             * it makes dialing SIP/${EXTEN} for a peer that isn't defined resolve to an IP that is
             * almost certainly not intended. It is much better to just reject purely numeric hostnames */
            ast_log(LOG_WARNING, "Purely numeric hostname (%s), and not a peer--rejecting!\n", peername);
            return -1;
    } else {
