[Asterisk-Users] Newbie hardware question

[Chris Albertson]

One other idea is to go 100% VOIP.

Get rid of the incomming analog lines.  You can subscribe to
a VOIP service that will give you a POTS phone number and
route incoming calls to you using SIP.

In the office you buy 16 IP hard phones.  

Now everything is done over Ethernet and you've not got
any of those rj-11 jacks.  You are also down to zero
PCI cards in the computer.

You would however need to have a "bussiness grade" DSL line
or fractional T1 installed in the office.

I think the above may even be cost effective as you'd be
able to skip the expensive channel bank, and T400P.
16 IP phones (Grandstream 101) is "only" about $1200
