Welcome to the RingCentral Community

I am using ring central API to make a call. I want to change from phone number while calling using API. I am passing fromPhoneNumber in array, But it still showing default CallerID CNAM to recipient.

Code:

$rcsdk = new RingCentral\SDK\SDK($credentials['clientId'], $credentials['clientSecret'], $credentials['server']);

$platform = $rcsdk->platform();

$platform->login($credentials['username'], $credentials['extension'], $credentials['password']);

$resp = $platform->post("/account/~/extension/~/ring-out",

array(

'from' => array('phoneNumber' => '+1xxxxxxxxxx'),

'to' => array('phoneNumber' => $RECIPIENT),

'playPrompt' => false

));

Is there a way so I can alter this code and display a different number for a caller?

Thanks in advance
