Most of the time we are only using 3 of the lines for calling. If I
used VOIP termination for outgoing calls wouldn't I still need the 4
lines to receive all of our incoming calls? Also do I need to have an
IP phone to connect to a Wildcard TDM40B or could I just use the phones
we have right now? Thanks.<br>

<pre wrap="">Andrew,
Sounds like it could be a good fit for your needs. Although that
raises many questions as to how exactly you should deploy it. If you
have a good Internet connection to the office in question you could
perhaps use VOIP termination for your outbound calls instead of the
current 4 PSTN lines. This way if all 20 people on the system could
make calls at once or just 4 and you would only pay per minute on the
usage.
If you have good analog phones already then probably the channel bank
route is the best way to support that many phones. Otherwise you could
get IP Phones such as the Cisco 79xx , Polycom's or Snoms.
Hard to say really what's best without knowing more of how much phone
usage is in question and how much you would like to invest in an
Asterisk/VOIP solution.
Hopefully this along with the other posts you get on the list help you
on your deployment. I'd be curious as to what you finally decide on
after you weight the options.

<pre wrap="">Hi
I am interested in setting up an Asterisk PBX in my office with digium
hardware, and I just have a few questions in regards to what I would
need. It is my understanding that an FXO card is used to interface with
an incoming/outgoing phone line, and an FXS card is used for interfacing
with a phone within the system. Currently we have 4 incoming/outgoing
phone lines and would like to have 20 phones in the system. In order to
accomodate this, would you either reccommend having 1 TDM04B (4 FXO
modules on it) for the 4 incoming/outgoing lines, and 5 TDM40B (4 FXS
modules on each) for the 20 phones we would have in the system. Or
would you reccommend 1 TDM04B for the 4 incoming/outgoing lines, and a
T100P connected to a channel bank of some sort to connect to the
internal phones? If you reccommend the T100P and channel bank, where do
you suggest I get an FXS channel bank? Please let me know if I got any
of this mixed up (like if I got the FXO and FXS cards mixed up) and
thank you in advance for your help in us deciding the hardware we need
for a new PBX.

P.S. We are currently using an X-Like software phone with a free world
dialup account for communication with our other office in a different
city. My question is if I can configure the extensions.conf to connect
to a free world dialup number when executing a dial command, or would I
need to edit sip.conf as well or some other configs or is that even
possible? Thank you again.
