Hi,<br>
<br>
All of the back and forth of Analog vs VoIP handsets tend to ignore
some of the basic issues.<br>
<br>
What type of cabling is in place, does it need to be upgraded to do
Ethernet, etc.<br>
<br>
The "gateways" can be handy if there are many closets where the
wiring terminates AND you have Ethernet to these locations. That
being said you probably should have some amount of backup battery
power any location you put a gateway. You can also do this running
your own T1 lines to the closet and channel banks in the closet.<br>
<br>
If all of the lines come back to the same place, you only have to
have backup battery in a single location.<br>
<br>
I have seen enough hackish VoIP deployments, that I can see many
cases that Analog is cleaner. For example, IBM Type1 cabling, can't
run PoE, so they installed wall warts with each phone...<br>
<br>
You also have to look at the use case. Doing an "office" with
Analog is very different then doing a phone in each classroom at a
school, or even hotel phones.<br>
<br>
The channel banks, even if you have to buy multiple to get the right
cards, should average under $200 each, 8 port T1 cards are about $2K
each, total cost to service 22x$200 + 6x$1000 = $10,400, or about
$10 per port, and you should be able to do it cheaper then this.
This is of course using Ebay pricing, new would be much higher.<br>
<br>
The gateways run about $25-30 per port, even for the lower end (like
the Grandstream below).<br>
<br>
Cabling costs depend greatly on location, around here it averages
$100/drop in office environments, if your only doing one run to each
room, it gets even higher, this is where the real cost of using VoIP
handsets comes into play.<br>

That would be the expensive route. The inexpensive route would
be to buy FXS ethernet gateways, like this: <a

You could then get by with a single reasonably sized asterisk
box (probably two setup as HA) and no need for expensive cards
or complex channel bank setup. We have done many hotels this
way with great results.<br>

A PCI express card with four primary rate ISDN ports, each
linked up to a<br>
channel bank, will give you 120 analogue lines. So you will
need nine such<br>
cards; and for reasons of simple numbers of slots on a
motherboard, they will<br>
have to be split among three or more servers, linked to a
gigabit switch.<br>
<br>
You might end up getting a better deal if you bought 1000
hardware SIP phones.<br>
(You also would probably increase your personal
indispensability factor, into<br>
the bargain .....)<br>
