If connecting to a legacy PBX, all VG248 devices should be set to forward
MWIs to Async 2. See the
page 5-25.
At least one VG248 per cluster should be set to forward MWI commands to
Cisco CallManager. See the
section on page 5-24.
If you are not using a legacy PBX, set the VG248 systems to forward MWI
commands along the Async 2 connection. You do not need to set this on the
VG248 system furthest away on the SMDI chain from the voice mail system.
That VG248 device should be configured to forward MWI commands to
Cisco CallManager. See the
page 5-25.
If the VG248 is set to forward MWI commands to Cisco CallManager, you
must set the MWI directory numbers in Cisco CallManager. See the
"Identifying the Directory Number for Setting MWI on Cisco CallManager"
section on page 5-26 and
MWI on Cisco CallManager" section on page
