Dear Concern,
Very good day. I am working on voipswitch last six years. I have web based callshop module. On web based callshop you can monitor Live call (active call), Cabin or booth wise bill and CDR, can create Invoice, can add trffic many more.
I have my own voip company. I have two running voipswitch and one asterisk softswitch. So I can support you very smoothly from ready module. If you want I can show you live demo.

Thanks and regards
