When I send a call from FreeSWITCH to Asterisk, I cannot get Asterisk to properly display the caller ID. I have my FS set to register to Asterisk as a Gateway like sip:00019924@testdomain.com. Asterisk always seems to use the '00019924' in FROM: 00019924@testdomain.com as the callerID. I tried setting the 'sip-force-user' directory variable but that did not work.
