Amı 发起调用与发送上下文不同的上下文

Question

我正在将 ami-io 库与 Node.js 一起使用。我正在发送带有上下文的发起呼叫，用于将应答的呼叫重定向到 ivr。有 2 个 ivrs 用于不同目的。另外，我将 Lead_id 设置为通道来处理结果，但上下文存在问题。即使我发送了自定义上下文，呼叫也会使用 from-trunk-sip-{callerid} 上下文进行。因此，我无法将 Lead_id 设置为频道。我的上下文仅在应答呼叫时才处于活动状态。我想设置 Lead_id 来引导呼叫是否被应答。

这是上下文和 ami-io 代码。

背景：

[type1-ivr-forward]
exten => _X.,1,NoOp(Calls for IVR)
   same => n,Set(LEAD_ID=${IF($[${LEN(${lead_id})} > 0]?${lead_id}:UNKNOWN)})
   same => n,Set(CHANNEL(accountcode)=${LEAD_ID})
   same => n,NoOp(Lead ID: ${LEAD_ID})
   same => n,Answer()
   same => n,Goto(ivr-1,s,1)
   
[type2-ivr-forward]
exten => _X.,1,NoOp(Calls for IVR)
   same => n,Set(LEAD_ID=${IF($[${LEN(${lead_id})} > 0]?${lead_id}:UNKNOWN)})
   same => n,Set(CHANNEL(accountcode)=${LEAD_ID})
   same => n,NoOp(Lead ID: ${LEAD_ID})
   same => n,Answer()
   same => n,Set(CALLERID(num)=${customer_phone})
   same => n,Goto(ivr-2,s,1)

Node.js

async function call(lead_data) {
    var action = new amiio.Action.Originate();
    action.Channel = `SIP/${lead_data.caller_id}/${lead_data.phone_number}`;
    action.Context = `${lead_data.type}-ivr-forward`; // type 1 or type 2
    action.Exten = '1003';
    action.Priority = 1;
    action.Async = true;
    action.WaitEvent = true;
    action.CallerId = `${lead_data.caller_id}`;
    action.Timeout = 30000;
    action.variables = { lead_id: lead_data.lead_id, customer_phone: lead_data.phone_number };
    client.send(action, async function (err, data) {
        if (err) {
            // success actions
        } else {
            // error actions
        }
    });
}

如果您想在第一段应答之前控制任何操作，您应该通过环回 - 本地通道拨号，而不是通过 SIP。
