Dear Bogdan,
Thank you for your tips. It is very wonderful messages for me.
I still have a question about acc tables(CDR). The sip methods INVITE and BYE will be recorded into acc when I make a call and hang up.
Is there any good idea to merge them into one record for billing issue?
I study the acc and mysql module, but I don't know which is the best way to change the INSERT SQL command to UPDATE SQL command.
Can you give me some tips?
Best regards,
Charles
