网络工程 - 来自 PSTN 的来电不会转发到手机号码 - 吾爱随笔录

我们将 Cisco 2921 连接到带有 Call Manager Express 的 T1 ISDN PRI。我们使用的是 CP8861 SIP 电话。一切正常，呼入呼出。为了更好地说明问题，这里有一个例子：Bob 有一个 DID 分机 101。当他在电话上选择前转所有选项时，他想将呼叫从他的分机转移到他的手机 9.......。安娜有分机 102，她在分机 101 上呼叫鲍勃，然后呼叫转移到他的手机。但是，当 Bob 的客户 Charlie 从 PSTN 呼叫他到他的 DID 分机时，Charlie 收到一条消息，说“此电话号码不可用”。

有任何想法吗？简而言之，电话可以将来自内部分机的呼叫转移到手机，但不能将来自 PSTN 的呼叫转移到手机上。

省略了一些带有私人信息的行。
