I am having issues setting the caller id on outbound calls from an asterisk box. I have set the caller id in the dial plan etc., but cid on receiving phones still shows the carrier's phone number. All calls to extensions managed by server are showing the correct caller id but when I place a call through the carrier, it shows their DID. They have assured me they are set to allow me to set caller id and have asked that I "provide a trace on the outbound calls to determine if the FROM in the IP header is correct."
How do I do this on Linux Ubuntu?
I am a newb with linux and with tracing IP packets.
Thanks a million!
