How to pickup a call from a waiting queue
Hi everyone. I have the following problem (and not sure if it's possible to implement it): There is a waiting queue that routes any incoming call to a user. When user is busy and another call arrives, it is put on hold until the user is available again. Is it possible to signal this waiting call to a pickup group of users (without ringing signalling), who can potentially pick and answer to this waiting call? Where can I find a reference?
Thank you very much indeed.
