[cisco-voip] a stack of VG224s vs C3945-112FXS/K9

[Scott Voll]

Are there any other features eg. Super G3 Fax that the 39xx supports that
the VG's don't.

ISR2's are NOT going anywhere any time soon.  I would be interested to know
if Cisco came out with this package, how long it will be before the VG's get
EoS/EoL as that seems to be Cisco's way.  Bring out a replacement, then EoX
the old stuff.  Might be worth talking to the AM/SE about cisco's plans.  I
would hate to put out a bunch of $$$ and then have it EoX a month
later....... Been there, Done that.

Just my 2 cents.  (and we all know how much that's worth in today's economy
;-)
