Mail Interface Module)
The VMIM (Voice Mail Interface Module) provides mid-range Auto Attendant/Voice Mail services for
the iPECS, primarily intended to support the MFIM600 but can be employed with any MFIM. The
VMIM contains a processor and DSP circuitry to support 8 simultaneous channels and memory to
support 9 hours of voice storage capacity. To provide additional channels and/or storage capacity,
up to three (3) VMIMs may be installed in systems with an MFIM600 for a maximum capacity of 24
channels and 27 hours of storage. For other systems a maximum of two (2) VMIMs can be
supported for a maximum capacity of 16 channels and 18 hours of storage. In addition to Auto
Attendant and Voice Mail functions, the VMIM also provides ACD announcements as well as Pre-
defined and Custom Message Voice announcements. The VMIM can support various codecs
including g.711, g.729a, and g.723.1.
The VMIM includes a 10/100 Base-T Ethernet interface as well as packet voice processing
