Call

Call is a generic term referring to any request for public safety assistance, regardless of the media used to make that request. This term may appear in conjunction with specific media, such as “voice Call”, “video Call”, “text Call”, or “data-only Call” when the specific media is of importance. The term “non-interactive Call” refers to an emergency Call that is initiated automatically, carries data, does not establish a two-way interactive media session, and typically does not involve a human at the “initiating” end.
