I can successfully copy the following into a URL and it works. (password changed)
https://service.ringcentral.com/ringout.asp?cmd=call&username=17274003201&; ext=7001&password=xxxxx&to=&from=17274106584&clid=7274003201&prompt=1
I was told I should use this format:
https://developer.ringcentral.com/api-docs/latest/index.html#!#RefRingOutCall.html
What would the complete string look like? I do not see in the https://developer.ringcentral.com/api-docs/latest/index.html#!#RefRingOutCall.html where a password is inserted?
