[cisco-voip] Unity PIMG

[Johnson, Ken]

I have a question for those of you with Unity-PIMG experience.  We
continue to run our Unity 4.x infrastructure on both the native
CallManager integration and a Dialogic integration with analog ports on
our NEC NEAX 2400 PBX.

 

We are realizing that as we migrate to Unity 5.x it may be time to put
the Dialogic out to pasture - especially to allow us to get off Windows
2000 - however we're also wondering if we'll see any management or
performance benefits by making this change.  Most specifically - since
we currently only have 10 analog ports on the PBX - we're wondering if
we would be best advised to migrate down to the 8-port digital station
version of the PIMG or go with the T1.  Our preference is T1/PRI
interfaces historically mainly for integration of caller number
information, etc - but we weren't sure if the digital station would
include this capability as well (i.e. with either PIMG solution will we
be able to eliminate the serial signaling interface for calling number
delivery?

 

Any other reasons we should either be hesitant to make this change
and/or choose the T1 solution vs the digital port version?
