Centos 来自res_odbc的错误

我已将odbc连接到MSSQL服务器，并从中获取sip帐户和拨号计划，我还可以在两个对等方之间进行呼叫，但asterisk得到错误：

正如星号中明确指出的，您有转义字符的选项，这可能在您的配置中设置不正确

在示例配置文件中：

; Is the backslash a native escape character?  The default is yes, but for
; MS SQL Server, the answer is no.
;backslash_is_escape => yes

如果您更改了该参数，但仍然不起作用，我认为您应该调试源代码，以查看该参数在您的星号版本中是否起作用。在21天内自学c/c++并阅读星号源代码。您对“如何调试源代码”的问题有何期待？当然你需要知道编程的基本知识，因为我在星号13.3.2上收到了相同的警告信息（来自官方软件包）。操作系统：CentOS 6.7
