San Jose, California-based Centigram Communications Corp reckons that it is the first company to make available the new AMIS-Analogue protocol for its products: AMIS-Analogue is a protocol designed to enable voice mail systems from different vendors to exchange voice messages and is scheduled to ship this quarter; the company notes that AMIS-Analogue is one of two protocols being specified by a group of 36 voice mail service providers, end users and vendors, the other being AMIS-Digital, for large or high-traffic systems; AMIS-Analog supports sending, receiving and replying to messages using Dial Tone Multi-Frequency signalling and analogue transmission and Centigram has initiated a two-phase testing process with other voice processing vendors – peer level testing in the lab, followed by testing at customer installations; when it becomes available, the AMIS-Digital protocol will integrate with the X400 message handling standard, supporting more services and offering greater functionality.
