Asterisk does pass the caller ID for the internal calls, but for the
external ones, my default outbound CallerID gets used.

I can set a different CID like you suggest above, but I don't know how
to get the inbound CID so I can set it correctly. Does anyone know if
there's a variable exposed to my extensions.conf so I can do something
like Set(CALLERID(num)=${VAR}) and set outbound callerID to that of
the calling party?

Thanks,
