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.
We do not do it. We specialize in the core SIP infrastructure for big
setups and our customers typically do not need to terminate calls
(either because their users have to subscribe to the service or they
have flat-rate plans).
In my opinion there is no way prepaid calling can survive in long
term. Prices of PSTN calls will keep falling, more and more calls will
be pure IP and the rest will be covered by flat rate monthly fees. It's
happening now and it will be more and more common in the future.
