上图中的Call Redirect选项不生效

解答：

参考思科文档，得出原因如下：

默认的CUE Transfer-mode是blind，该模式下CUE并不侦测电话的状态，所以必须将模式更改为attended或semi-attended才可以。

配置如下：

1. config t

2. ccn subsystem sip

3. transfer-mode {attended | semi-attended | blind refer | blind bye-also]}

4. end

5. end

6. show ccn subsystem sip

attended - Transfers calls in attended mode using the REFER method. The transfer is completed when the destination extension answers the call.

semi-attended - Transfers calls in semi-attended mode using the REFER method. The transfer is completed when the destination extension is ringing.

blind refer - Transfers calls without consulting using the REFER method.

blind bye-also - Transfers calls without consulting using the BYE/ALSO method.

CiscoUnity Express uses this method if the remote end does not support REFER. This is the default value.
