Adding or removing VoIP modules: MP20 and MP80

The G450 main board has four slots for VoIP engines. Each slot can accommodate either an
MP20 (Media Processor 20) module or an MP80 (Media Processor 80) module. An MP20
provides 20 channels, and an MP80 provides 80 channels. However, the G450 supports a
maximum of 240 active channels. Therefore, the following number of active channels can be
supported: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, or 240. Note that 220 channels cannot
be supported.
