Welcome to the RingCentral Community

Hi Keith,

1.) Add users to Sandbox:
 
You can Add Users without Phones



2.) Login to Softphone With the User ( Sandbox Environment )

Login to Softphone using:

• sandbox number
• extension number ( {three digit} to {five digit} number)
• password

OR

• direct number or digital line associated with a user
• password

To know how to configure your Softphone to point to Sandbox env , please read the getting started guide here:  ( under Your Softphone )
https://developer.ringcentral.com/library/getting-started.html 


3.) Initiate a Ringout using API 

Use RingOut API endpoint to initiate a Ringout, a simple example is below:

POST /v1.0/account/~/extension/~/ring-out  
{
    "from": {
        "phoneNumber":"sandboxnumber*extensionnumber"
    },
    
    "to": {
            "phoneNumber":"toNumber"
    },
    
    "playPrompt": true
}

More information on RingOut API could be found here:

API ref: https://developer.ringcentral.com/api-docs/latest/index.html#!#RefRingOut.html
API explorer: https://developer.ringcentral.com/api-explorer/latest/index.html#/RingOut

4.) Check call-logs data created in service web

Login to service web and navigate to Call Log tab to see the data.

I have installed the Desktop Soft Phone Application and I have it connected to my sandbox, but it will not make out going calls.
Cannot initiate Ring out call.

Do I add a user with or without a phone?  After I select my state I don't get zip codes, the box is grayed out.
Steps on how to generate call logs and setup a user would be nice.

You need to add a user and make calls to the number that is assigned to the sandbox account.
