Do you mean what is displayed on the phone's display? If so, yes, with
some phones this is possible, by performing a re-INVITE or UPDATE with
the new caller information included. However, Asterisk currently has no
way to request that to happen, it only knows how to send
re-INVITE/UPDATE to change the media path.
