如何配置两个Twilio拨号号码

Question

type TwilioMakeCallTwiML struct {
    Say     *sayTwIML  `xml:"Say,omitempty"`
    Play    *playTwIML `xml:"Play,omitempty"`
    XMLName xml.Name   `xml:"Response"`
    Dial    struct {
        Say      *sayTwIML `xml:"Say,omitempty"`
        Timeout  int `xml:"timeout,attr"`
        CallerID string `xml:"callerId,attr"`
        Record   string `xml:"record,attr"`
        Number struct {
            StatusCallbackEvent  string `xml:"statusCallbackEvent,attr"`
            StatusCallback       string `xml:"statusCallback,attr"`
            StatusCallbackMethod string `xml:"statusCallbackMethod,attr"`
            PhoneNumber          string `xml:",chardata"`
        } `xml:"Number,omitempty"`

    } `xml:"Dial,omitempty"`
    DialVoice    struct {
        Say      string `xml:"Say,omitempty"`
        CallerID string `xml:"callerId,attr"`
        Record   string `xml:"record,attr"`
        Number struct {
            StatusCallbackEvent  string `xml:"statusCallbackEvent,attr"`
            StatusCallback       string `xml:"statusCallback,attr"`
            StatusCallbackMethod string `xml:"statusCallbackMethod,attr"`
            PhoneNumber          string `xml:",chardata"`
        } `xml:"Number,omitempty"`

    } `xml:"Dial,omitempty"`
}

ttwilio.TwilioMakeCallTwiML field "Dial" with tag "Dial,omitempty" conflicts with field "DialVoice" with tag "Dial,omitempty" HTTP|2018/03/12 16:23:21 |[::1]:49370|POST|/ttwilio/receiveIncomingCall|500|21||TwilioProxy/1.1|18.924103ms|
