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?

1. Using digital cards from Digium and possibly other mfg.
2. Using ATA (Analog Telephone Adapters)
3. Using IP phones
4. Using Soft phones
5. 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.
