Hi All,<br><br>Do you'll have any recommendations on a Linux based Customer Management and Pre-paid Billing system for Asterisk, Freeswitch or Kamalio?<br>The system should also allow customers to register, login, buy more credit, view call records, etc.<br>
<br>Commercial or Open-source are ok as long as they run on Linux.<br><br>Thanks,<br>A.<br><br>
