My current setup includes Asterisk 1.6 and a digium FXO card. Everything works fine. Caller ID is working. The only problem is that when no caller ID is present, asterisk sends a default FROM address of “email@example.com” (where 192.168.1.xx is the SIP server address).
Is there any way to change the default that gets sent when there is no caller ID? I would like to change it from “asterisk” to “Unknown”
