We have Advanced Voip Billing and Advanced Radius on a server and we need to fully implement it with our Cisco 3745.
We currently want to use it for a wholesale customer and want to make sure the customer can't make calls once their funds have run out (pre-paid).
You should also know TCL and IOS for VoIp of course.
Would like you to be local as we would like you to work out of our office in Markham if possible.
