[asterisk-users] CDR Question

[jg]

"lastdata" is the argument string of "lastapp". Since Hangup() does not 
have any args, "lastdata" is empty. If you need to store things that are 
not already stored, you can either use the "userfield" or add extra 
columns to the cdr table, which depends to some degree on how you store 
the call data. Details can be found here:
