[asterisk-users] read write or only read fields in cdr?

[Bayrouni]

Hello,


I created a new field named pre_dst of type varchar(80) exactly like dst
 field in cdr table.

In the dialplan I put:
exten => _7.,1,Set(CDR(pre_dst)=${EXTEN:1})

and when I call, all goes fine except that pre_dst has always NULL value
in cdr.

Do you know why?
Is something wrong I did?


I know that original fields in cdr are only readable, but in this cas
pre_dst is one I created myself !!!

Thank you.
