[Asterisk-Users] FXO cards - low cost systems

I think this is a great solution...I'm doing the same thing.
The only snag I'm running into is finding a VIOP provider that will
provide DID numbers in my local calling area! (Spokane,WA area code:509)
You might want to double check that you can find a VOIP provider that
will give you a DID for your local calling area.

Comments on this are welcome. Here is my opinion...
I just went through this. Your office size is not economical. Actually
smaller or larger would be better. Getting a channel bank and then
using only 8 ports is a waste. OK if you have 24 extensions but 3x to
expensive if you only use 8 ports.
I'm working on a 3x8 system for a not-for-profet I'm doing the work for
free and they value every cent as they live off donated money. (You
don't want to tell donors that 100 of their $20.00 checks went into a
new PBX and did nothig to save sick homeless kids or whatever.)
Here is what I told them: "Go VOIP". You can get decent IP phones like
BT100, or whatever for $65 to $100 each. Buy eight of these.
Next get a VOIP service provider to provide you with a PSTN DID (A phone
number) VoicePulse will do this for about $8.00/month pluss outgoing per
minute cost. So you get as many incomming lines as you need and you have
zero hardware interface at your site. (other then your DSL line.)
Keep one or two analog POTS lines and use one or two FXO cards either
Digium other. You want POTs for free local calls and for 911 calls and
for if the VIOP service fails or if the DSL line is down. But one POTS
line for the whole office is enough
So now your Asterisk server is just one re-cycled PC with one FXO card
installed, nothing else. Pretty dard cheap.
If using a "re-cycled" computer as the server _do_ keep
spares on site. You don't want a broken power supply fan to crash your
phone system for a day. I'm suggesting a full-up hot spare Asterisk
server system be kept on-site.
