+I've had some people ask me "how do you spoof your caller ID yourself?" Well, here it is...
+
+1. Find an IAX or SIP provider that is asterisk compatible
+2. Install asterisk
+3. Install Festival or SWIFT. I prefer SWIFT, but for those who dont want to pay, this one works for Festival. Replace 'festivle' with 'swift' to make it use SWIFT.
+4. Edit your extendions.conf somehow to have:
+ exten => XXX,1,Answer()
+ exten => XXX,2,AGI(/etc/asterisk/spoof.agi,${CALLERID(num)})
+
+ Where XXX is your internal extension number
+5. Edit the 'trusted' array to include the caller ID's and extensions of folks who will be allowed to execute this script.
+6. Get permission to test, dont break the law, and then try it.
