Wow, it's been a while since I had written anything....
Anywho ..... We just closed a banking IPPBX project. The bank has many branches throughout Malaysia and an overall of 2000+ users.
We've got back-end integration into the banking system and future planning of integrating Asterisk for automated self-help services for their customers using our very flexible IVR.
If you would like to know more about this project, drop me an email.
