Hi,
I am Shan with tele-pixel, We have a ready made product which I can show a demo with the following features
HOW IT WORKS
* ISO will be provided to install in the gateway machine , which is a LINUX based
* we provide a web interface to monitor the live calls, CDR, ACD etc.,
* Through the interface you can configure new rate plan, new users map user IP etc.,
BENEFITS:
* just need 7 KBPS per call per minute with 2 MBPS speed
* use different protocol to save blocking
* IP never get block because of encrypted VPN
* good ACD
* Auto provisioning during installation
Thanks
Shan Jay
