Audio Messaging Interchange Specification (AMIS)
An enhanced key system feature for voice/call processing that enables enterprise locations to transfer and forward voice messages between systems.
Abbreviated and regularly referred to as AMIS, the Audio Messaging Interchange Specification is a standard that allows the transmittal of intact voice mail messages between voice mail systems of different vendors - allowing a user to "forward" a voice mail message to a user on a different voice mail system (in a different geographic area, or conceivably, at a different company).
Developed in 1992, AMIS saw its heaviest use prior to the wide-scale adoption of e-mail, as it was the fastest way to get urgent or time-sensitive messages to large numbers of people (e.g. A sales team with a "broadcast" message).
