I believe that's what you want.  And then you specify the caller id you want to use in the callerId query parameter.  It works like a champ.  I can change this easily for what ever customer I'm making the call for.

Thanks ... with the clue that /channels/{newChannelId} works, I was able to go through the asterisk source and find out what it did with the callerId parameter that was different from setting CALLERID(num).

It turns out that chanel callerId is specified it effectrively sets CALLERID(num), CALLERID(num_valid), CONNECTEDLINE(num) and CONNECTEDLINE(num_valid).

And it seems that, in order to get the value set in the SIP INVITE's From header, the important thing to set is actually CONNECTEDLINE(num)
