Adding a Phone number in conference

Question

So I'm trying to use Sinch API for making a calling application. I'm using this to make a conference call, but the call is only made to first person and plays the message that "You are the only person in this conference" and hangs up after a while. Documentation writes that The same API can be used multiple times to connect multiple phone numbers in the same conference room. But couldn't made to do the task. Also contacted the support but no answer yet.

Any help will be appreciated.

    "method" : "conferenceCallout",
    "conferenceCallout" :
    {
        "cli" : "46000000000",
        "destination" : { "type" : "number", "endpoint" : "+14154251021" },
        "domain" : "pstn",
        "custom" : "customData",
        "locale" : "en-US",
        "greeting" : "Welcome to my conference",
        "conferenceId" : "coolconf",
        "enableDice" : false
    }
}

and then

{
    "method" : "conferenceCallout",
    "conferenceCallout" :
    {
        "cli" : "46000000000",
        "destination" : { "type" : "number", "endpoint" : "+15612600684" },
        "domain" : "pstn",
        "custom" : "customData",
        "locale" : "en-US",
        "greeting" : "Welcome to my conference",
        "conferenceId" : "coolconf",
        "enableDice" : false
    }
