I'm a total newbie at this telephony stuff but I'm putting together a
low
cost PBX for my small company and wanted a check on the h/w I'm planning on
ordering and my system configuration. Any input is appreciated. Take it
offline and email me directly if appropriate (mstupak@comcast.net). Here's
what I'm planning:
=== Parts List ==
1 Digium Wildcard TDM400P w/ 4-port FXO bundle
I'm planning on using this to connect to a few CO POTS lines.
A mid-range computer (600MHz or so w/ 512 MB RAM)
Some form of Linux (fedora?)
Asterisk
10/100 Ethernet card (in the computer)
10/100 Ethernet Switch (8 port or so)
A few SIP capable phones
=== End Parts List ==
And now a few questions:
1) Is this a feasible system? Am I missing any important hardware?
2) What is a good Linux to use? I'm reasonably proficient w/ Linux.
3) Do I need to tell the phone company anything special or do I just
have them connect up standard phone lines?
4) Can the phone company usually roll the calls onto a spare incoming
CO line? (e.g. if the first line is busy - route it to the second line, if
the 2nd is busy - route to the 3rd, etc.) Is there a special name for
feature this that the phone company will recognize?
5) I'd like to support a special feature - I'd like to have 2
different incoming phone numbers (on all lines) and have asterisk multiplex
to the right voice menu system based on the incoming phone number. Is this
possible? Does it require special features from the phone company?
That's all for now (though I'm sure this won't be my last post.
Thanks
again for any help.

Looks good to me.
You will want hunting or call forward busy on the phone lines you order. Mine
costs $1.15 per month

Question 5 will be harder.
What you need is DID ( Direct Inward Dialing)
Not available in my area with regular phone lines.
Perhaps it could be done with distinctive ring?????

We have 4 incoming pots lines with 4 numbers. When number 1 is busy it will forward to the next line. If that one is busy it will forward to the next. The only thing I have run into as a problem sometimes people dial back the number they got called from. If that is the last number we have and it is busy even if line 1/2/3 are free line 4 will not forward back to 1. For some reason our phone provider will not do that.> 5) I?d like to support a special feature ?
