Abstract
A platform for supporting telephone netrwork applications includes Network Interface Units (NIU) for interfacing between the telephone network and the platform. A disk storage system stores voice messages to be sent over the network and voice messages received from the network. Voice messages are conveyed between the NIUs and the disk storage system by Voice Interface Modules (VIM). The platform is installed on a general purpose digital computer and includes an Application Interface Module (AIM) responsive to an AIM command set including: SEND VOICE MESSAGE, CONNECT CALL, COLLECT DIGITS, INITIATE CALL, TERMINATE CALL, GET MESSAGE NUMBERS and PIVOT CALL. In response to SEND VOICE MESSAGE, a designed message stored on the disk system is sent to the network via the VIM. SEND VOICE MESSAGE has a RECEIVE VOICE MESSAGE option whereby a message is received from the network after the SEND data is transmitted and stored on disk. The platform initiates a call to the network in response to INITIATE CALL and an application is informed of an incoming call to the network by an INCOMING CALL Response from the AIM to the application. DTMF digits entered during a call are returned to the applicatio…
