that capacity is used for the ACD service (Since two languages are
supported, two minutes for each language). and two minutes of it for the
system message recording. Besides, the module includes a DRAM memory
that can store 34 minutes of messages, so that it serves the users with voice
mail message boxes. By this way, any extension with the necessary
authorization can leave message for the party s/he calls, as if there is an
answering machine on the phone of that party.
The module has been designed in a structure so that it can be directly
integrated onto the exchange. There exist 6 capacity expansion slots on the
card. Two of them are used for EVM-FL, and four of them for EVM-DL.
