That will be difficult. You cannot set a channel variable on the parent 
channel from inside the child channel. At best, you can pass the parent 
channel's name into the child channel, then in a macro run by Dial() you 
can store the Call-ID into the database keyed by the parent channel's name.

However, none of this will work if you dial multiple SIP channels, of 
course.
