dear Don & the rest,
Imagine:
*replacing all that wiring
*buying 300 first-generation VoIP hardphones at $100 each
*(regularly?) updating the firmware on each one.
Why not get VoIP<->analog gateways?
That way *centralizes administration* and lets users keep their (higher
quality) analog phones.
The Patton Smartnode 4900 ($4500) should allow this:
(diagram only makes sense in a monospaced font)
ISDN SIP FXS
PSTN <----> Asterisk <---> Smartnode <----> analog phone
T1 eth cat3
I'm working on a telephony upgrade for my office too and this approach
makes more sense to me -- please comment!
(also, Don, there are probably gateways with more FXS ports -- say 60
instead of 32 -- that would make this more cost-effective for your 300
phones)
