I need to be able to collect information (e.g. customer account #) via an IVR (e.g. using VAD), store it in a db, and then be able to retrieve it when the call is transferred to an agent. Questions: 1) Does each call have a unique identifier that I can store in a db (using the VAD database component) during the IVR flow? 2) When the call is xferred to the agent, is that same unique identifier available that would allow me to retrieve the stored information and then use 3cx assistant to launch a URL with the retrieved parameters?
