twilio同时拨打客户端和号码

<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Dial>
        <Client>clientNameAndroidPhone</Client>
        <Number>+1xxxxxxxxxx</Number>
    </Dial>
</Response>

when I call the number that runs the above code. Both my android client and phone number ring. If I answer using android, it looks like it accepted the call... but nothing happens. The actual number keeps dialing. If I answer as number -- it works fine.

Now if use just the client

<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Dial>
        <Client>clientNameAndroidPhone</Client>
    </Dial>
</Response>

The code above works fine.

I have tried this using Twiml bins and using php server.

I also want to add that when I use both number and client. The outgoing call to client is never logged in my call log.

Anyone ever run into this?
