[Serusers] Broken Calls not written to Database - sr-users

12 Jul 2005


      Dear List,
I'm making a call to PSTN, it's okay i can talk with the other party via ATA, but suddenly i unplug power from it, and in accounting module it does not write line with BYE message so i cannot understand whether the call is finished or not. only INVITE and ACK are written, no BYE :(
This may be a security hole for customers, because they talk for a long time and they may unplug their units or cut power so it does not tell SER it's over. How i can prevent this, also what i need to add as a line for telling ACC module not to write calls from 833 to 833 into database, which are free SIP2SIP calls ?
Btw, a Postpaid Billing System is on the way for OpenSER built in PHP, later i will need OpenSER group's help to place it onto hosting site. Shortly it will have features:
* Nothing extra from package, default MySql Database which comes with OpenSER Release is being used,
* All routing is done via OpenSER's ser.cfg ,
* Initial Rate, Initial Time, Increment Rate, Increment Time will be user variable ,
* Account Creation/Deletion done in PHP ,
* Invoice Generation and CDR will include many variables ,
* Rating will be in PHP,
* And everything is totaly free :)
If you have ideas and/or suggestion please write back to me so i can work for it too.
Reqs: OpenSER & PHP & MySql & Apache
Thanks,
Ozan
