Emergency Call Recording or Flagging for Bomb Threats/Active Shooter Etc

We are running the following scenario, What should our company do if there is a bomb threat that gets called in to us? At a previous job I had there was a number we could dial immediately after the call to save/flag that call. I request RingCentral to add such a capability so that in the event that such an event happens users can dial a number (pref a #hash number) that way the call can be saved for police to follow up with in an investigation into such a call.
