Is there a way to have the caller, transferee and call transferring to all be connected on the call and when transferee has finished can hang up and call still be active?
Are you looking for a solution to do that using RingCentral apps or using the platform API?
Using the app, while on a call, you can click the Add (+) button, which allows you to make a new call to a new party, then you can merge the call so 3 parties can be on the same call.
If you want to do this using API, you can use the bridge call party API to merge the calls, provided that, you have got the calls' session Ids and party Ids properly.
Using the RingCentral Phone for Desktop, you can dial or receive test calls, send and receive test SMS or Fax messages in your sandbox environment.

Tip: switch to the "sandbox mode" before logging in the app:
