Im' a linux geek (many years), but an asterisk newbie (less than a week). Anyway, this is what
I've get and done (my setup is fully experimental, just to learn, then scale to a full 35
users/ 8 PSTN lines setup for starting). All of this are my notes. Previous: Definition of FXS, FXO:
<A HREF="http://www.3cx.com/PBX/FXS-FXO.html">http://www.3cx.com/PBX/FXS-FXO.html</A>
NOTE: I assume no responsability, if you damage one equipment or person or cat. You are working with
voltages which get sometimes higher as 100 volts. Dogs know nothing about telephones.
I have:
* studied a lot. DO THAT. if you find an error, you will not find the cause if you do not know
where to look, where to change something, where to disable something.
* Someone ponted me to this document, which I started with. Nice to start.

* Fedora 9 (my desktop and the same at home). IP: 192.168.1.141. IPTables disabled.
* installed asterisk as a fedora root user:
        # yum install asterisk asterisk-sounds asterisk-voicemail
I bought:
* 1 Linksys SPA3102 (1 FXS, 1 FXO)
* 1 Linksys PAP2 (2 FXS)
* 3 old panasonic analog telephones
* 1 telephone line (also called POTS, PSTN) from my city provider.
* Connected between them (easier as connecting your microwave oven). Phones go to the FXS/PHONE ports.
POTS/PSTN go to the WALL/LINE/FXO port. Ethernet ports go all to a hub. SPA3122 yellow port keeps
empty.
* Programmed them first with a telephone connected (both Linksys features a menu with voices):
Enter voice menu ****

(Hangup: ATA will reboot)
(192.168.1.223 is the SPA3102, 192.168.1.222 is the PAP's. All IPs must match your office's)

* Ok, now to configure asterisk in the fedora BOX:
# vi /etc/asterisk/sip.conf
[101]; port 1 FXS on PAP2

regexten=101

[201]; call from FXS extension --> PSTN

canreinvite=no
[201]; call from PSTN --> 101
type=user
host=dynamic
port=5061
secret=green
context=padep
dtmfmode=rfc2833
* extensions.conf, commented, contains:
        [padep]
        Everyone of this three groups is for one extension. Means:
        - Connect the call to the extension
        - wait 12 seconds
        - go to voicemail
        - Hangup
        exten => 101,1,Dial(SIP/101,12,rt)
        exten => 101,2,Voicemail(101)
        exten => 101,3,Hangup
        exten => 102,1,Dial(SIP/102,12,rt)
        exten => 102,2,Voicemail(102)
        exten => 102,3,Hangup
        exten => 103,1,Dial(SIP/103,12,rt)
        exten => 103,2,Voicemail(103)
        exten => 103,3,Hangup
        exten => 104,1,Dial(SIP/104,12,rt)
        exten => 104,2,Voicemail(104)
        exten => 104,3,Hangup
        Voicemail
        When the user dials 500, has his voicemail menu
        exten => 500,1,VoiceMailMain()
        When an incoming call from PSTN-FXO-SPA3102 arrives, redirect to extension 101
        From PSTN to 101:
        exten => s,1,Transfer(101)
        When user dials 7#, starts an echo test
        exten => 7,1,Answer
        exten => 7,2,Echo()
        exten => 7,3,Hangup
        to get external PSTN line Dial 9#, authenticate with 1111#
        exten => 9,1,Answer
        exten => 9,2,Authenticate(1111)
        exten => 9,3,Dial(SIP/201)
        A simple test: dial 2# and get a "hello world" answer. I recorded my own voice, and put
        hello-world.wav in the sounds dir
        exten => 2,1,BackGround(hello-world)
        exten => 2,2,Hangup
        Some notes
        exten => _91XX!,11,Authenticate(1111); How to authenticate
        exten => _91XX!,20,AGI(agi.bash); How to run an AGI script
        exten => _91XX!,30,GotoIf($["${numero}" = "22"]?4:5); How to return the number from AGI script
        exten => _91XX!,40,Dial(SIP/201/${EXTEN:${GLOBAL(TRUNKMSD)}}); Dial a number like 9125, behind my panasonixPBX
        exten => _91XX!,50,Hangup; this is really complicated.
* Example for my AGI script:
        # cat /usr/share/asterisk/agi-bin/agi.bash
        #!/bin/bash
        checkresults() {
        while read line
        do
                case ${line:0:4} in
                "200 " ) echo "$line" >> /tmp/agi.log
                 return;;
                * ) echo $line >&2;;
        esac
        done
        }
RESULT='SET VARIABLE numero 22'
echo "$RESULT" > /tmp/agi.log
# former line is my log, to verify AGI runs....
echo "$RESULT"
checkresults
---------------------------------------------------------
That's all. I studied a lot, since saturday. You must do that, if you find an error,
I'm sure you will not solve it, if you didn't studied.
> Where do I connect the phones? to PC ? How to connect Linksys with PC ?
When you buy the ATAs (linksys), you'll find that easy as connecting your TV.
That's simple. Both include full-colored diagrams.
> Do you have a visio diagram or powerpoint that you can share with me
No. I prefer reading and writing. Read above. Read your equipment manuals.
Look for google images of the ATAs. Is really simple. You are worrying without having
read anything... Read, google what you don't understand from my mail.
Good luck. Ask, if you need something more.
