Need help with CDR and DAHDI


I need help with the CDR…i use an analog phone with Asterisk. If i pick up the phone and don’t dial anything or if i dial an invalid extension an “empty” CDR entry is generated :

dcontext: default
channel: DAHDI/1-1
dst: s
disposition: NO ANSWER

the ‘dst’ column is always ‘s’. Is there any way to avoid this?

i am using Asterisk on debian and odbc_cdr with mysql.

Thank you.
