[Freeswitch-users] dialplan variables in XML cdr

Hello, Is there a way to have some custom dialplan variables appear in the XML cdr output? We want to log some things about the call, such as what option was chosen, which carrier route, etc. I want to be able to set a value in the dialplan and then figure out what it was in the CDR so we can do reports on it later. The variables I set aren't in the <variables> section. Is there any way to enable this, or am I missing something? Thanks! -Tim
