Hi Sebastian,
I use a Perl script which runs my queries and disconnects any calls for
users that have run out of credit. The script then sleeps for a time and
loops back to the beginning of the script. Nothing clever!
I don't set a timer at the start of each call because there may be multiple
simultaneous calls using the same credit and I don't reduce the credit until
the call ends.
Regards
Stuart

Hi Stuart,
I'm with the same problem at this moment. I have a billing system on my
server with asterisk (credit, rates, call-cost, ...) and it works fine with
ser, too (with some TRIGGERS in the postgres database). I'm also able to
send "BYE" messages to the caller/callee to terminate the call... but I
still have to make it manually.
You wrote that have a process which runs periodically... how did you make
that? You wrote your own C-program? It would be nice to have a good command
line-timer in which you can put the sipsak command lines for every call...
Thanks
Sebastian

Hi Jan,
My solution for disconnecting calls where the customer has run out of
credit
is to use SER to generate a BYE to the gateway. I use
exec_dset and
exec_msg
from ser.cfg to store in a MySQL table some fields
from the INVITE and ACK
messages that setup the call. Then I have a process which runs
periodically
on my server that queries the table to find calls that
need to be
disconnected and generates, using the SER fifo, a BYE message to the Cisco
gateway which disconnects the call. Not very elegant solution but it
appears to work and I don't have to handle the media stream. I could also
send a BYE to the phone but I don't do that at the moment.
Please could you tell us about how you are solving this problem in
production systems? I expect you have a more elegant and professional
solution.
Regards
Stuart

I tried this a long time ago with a Cisco gateway. It worked, SER
did not let re-INVITEs through and the gateway terminated the call. We
are not using it anywhere in production.

I know there was some discussion in the recently
about using
session-timers as a method for doing prepaid. I'm just wondering if
anyone has actually played around with this, and what your experiences
were? My PSTN Gateways support session-timers, so I was thinking about
trying this.
