[Serusers] Ser CDRs

[Gregory D. Burns]

Guys,

I’m new with ser, but it seem great so far. The customer I’m working with
want to get reliable CDR’s from his SER SIP Server. He also has pre-paid
customers on it so it need to check to see if they have monies to make the
call, and when the call is done, it need to calculate and deduct the cost of
the call from their balance.

I have been using exec_msg command to try and do this, but I been having a
hard time getting it to work right because I get more then one invite’s and
ack’s. Also sometime they miss-dial and I only get Invite’s.

So I guess my is, are exec_msg’s the right way to go? Is anyone else doing
the same thing, if so could you share you config with me?
