[Serusers] Session-Timers for Prepaid

[Stuart Kirkwood - Jubilee Consultancy Limited]

Hi Iqbal,

My script runs every few minutes.  I don't use a disconnect time for each
call because there may be simultaneous calls using the credit from one
prepaid account.  

I too have looked at session timers but the gateways I'm using have the
minimum timer value set to 30 minutes which is too long for that to be my
primary method for disconnection but it is OK as a backup.

Regards

Stuart

Stuart, doing something similar here, wanted to know your cron setup if
possible, because each user would have a diff disconnect time, depending
on their credit left and destination dialed.

I looked at having variable session timers per user also, but havent had
the time to implement it as yet.
