[Serusers] Session-Timers for Prepaid

[Stuart Kirkwood - Jubilee Consultancy Limited]

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.
