The incoming line info needed is the same as the info you put into your FXO Adaptor.
So "add new external line"
Then:
Line Name: a name you want to call it
Server: this is the url after the @ sign in your SIP account i.e mine is 3011xxxx@sip.voipfone.co.uk so I use "sip.voipfone.co.uk"
ID or User Name: this will be your SIP ID i.e. mine would be 3011xxxx
Password: your password from your SIP provider
Incoming Calls Ring On Extension or Group: which ever extension or group you wish to use.
Save & now you have your incoming line.
Now set up your FXO adaptor as an extension using the "setup details" against the extension number you wish to use.
Hope this helps
