Hi all,
I have a question - can i use an Asterisk without any FXO or FXS cards? I mean, that i would like connect to my voip provider via Internet and connect clients with voip phones or software phones like X-Lite?
Thx for answer
yes you can. its already in the book of oreilly. that’s what exactly what im doing right now. 
Sigkill, can you please be more specific. I basically have the same question as this poster. What is your setup like then, and if you want to add phones, what would be needed?
- Using digital cards from Digium and possibly other mfg.
- Using ATA (Analog Telephone Adapters)
- Using IP phones
- Using Soft phones
- Any combo of above.
I have used #2 & 4 and both worked fine for me. Now that I bought 4 more ATAs off ebay, plus the 2 I already had I have enough lines for all rooms in house.
For setup of ATA, you need extension # and password for each one.
From admin menu in ATA put in extension and password as the account number ( or phone no) and password.
In the sip.conf
[extension no.]
type=friend
host=dynamic
context=default
;context=access-control
username=extension no.
; fromuser=extension no.
secret=pwd22
port=5060
callerid=“Bath rooms”
mailbox=extension no.@sias
dtmfmode=rfc2833
nat=no
canreinvite=no
; below are optional stuff for call pickup.
callgroup=1
pickupgroup=1

Oh, yea… . . . . you need a phone to plug into the ATA. Any vanilla phone will do. $8 special from Wall mart or whatever. Also the ATA WAN cnx needs to be connected to the asterisk via Cat-5 cable. I have a gingle CAt-5 jack on the asterisk computer. It goes to a 16 port swich. Those ports go to 7 ATAs and 6 computers.
