Hi fred,
For the branch office you could consider a 2 (or more) port E1/T1 card.
You can utilize one port for an incoming E1 from the telco (BT?) and
then the second port run to a T1 Channel Bank such as the Rhino 24 port
FXO http://www.myphonecall.co.uk/voip/channelbanks/rhino/default.aspx -
this is the closest to the 'hub' you describe.
You would need the cabling in your patch panel to break up the Rhino's
50-way 'telco' connector to something you can patch (rj45/rj11) or run
to your analogue phones. I don't have any recommendations for this as
I'm still looking at this for an installation.
This would give you an asterisk setup with ZAP channels 0..31 incomming
and 32..56 your extensions. You will have the advantage of reliable
faxing (ie with fax machines) with this solution instead of going to sip
phones and sip/ata/fax. I'm looking to do this in our office closer to
christmas - all mentioned hardware known to have good asterisk support.

Hi all
I am new to this whole field, being it PSTN or voIP. I am currently
reading the "Switching to VoIP" and "Asterisk: The Future of Telephony",
so hopefully, I will be less clueless soon :)
My first question: if I buy a Wildcard TDM400P, with one X100M and three
S100M modules, I would be able to have 1 telephone number given out by
my company to come in to my asterisk server, and I could plug in 3
analog phones onto that card, am I correct? Hence, do we have a 1-to-1
relationship here for either modules?
My second question: for a branch office of about 20 people, which E1
card do you advise? Would the TE210P be a good choice? (number of
concurrent calls would be max 10 for now) Why?
Thank you all.
Cheers
fred
