Hello
Thanks for the feedback from everyone.
You can try cdrtool version 6.6.0, I have added parallel prepaid call
support. The algorithm is described in PREPAID.txt
cdrtool (6.6.0) unstable; urgency=low
* Allow simultaneous calls for prepaid accounts, see the Simultaneous
prepaid calls section in doc/PREPAID.txt
* Added pseudo code examples for call control engine
* Apply the changes from setup/mysql/alter_tables.mysql
* Added interface to kill ongoing sessions in Prepaid page
Testing and feedback is useful and welcome.
Regards,
Adrian
