Fax line CallerID

I have a fully functional 8-port analog card in my asterisk server. I want to know how to set the caller ID for that card? All my other numbers caller ID is set. I just do not see where to set the callerID for the Fax lines I have plugged in.

You want to set outgoing CID? For an analog PTSN circuit, your telco should be setting outgoing CID.

Yes when I dial out on these analog devices it shows Unknown in the CallerID I just want to set all the Analog calls to be set to the same CALLERID.
