Programming Third Party VM, Analog Ports You can connect the DX-80 system to a third-party voice mail system using spare analog ports. Doing so occupies these ports and therefore reduces the number of system ports that you can use for the telephones, FAX machines, modems, etc. Comdial recommends using the DX-80 DX-SO voice mail system, because it is a digital integration and therefore does not occupy valuable analog port space of the DX-80 system. For further details, see Section 9.2, Programming Optional Internal VM, Digital. Using voice mail greatly enhances the use of the DX-80 system. Features accessible when voice mail is installed vary depending upon the third-party product connected. Features that the DX-80 system accommodates include the following. • Automated Attendant • Extension unique voice mailboxes • Call Forward to extension voice mailboxes • Answering Machine Emulation • UCD Queue Announcements • Menu Routing • Voice Record • Automatic Voice Record • Specific CO Line Greetings on Automated Attendant The following conditions apply to analog voice mail. • Voice mail feature operation is limited only by the ancillary voice mail system. • When voice mail ports are used heavily (high call traffic), the system updates message indications notably slower than usual. • When VM messages are waiting, the system flashes the auxiliary lamp green.
