I want's to develop and test a managed [C#] application for office communcation server
psudo code is
// Sample application logic to enforce maximum number of audio/video calls
// between two zones as defined in the Zone Configuration Table (ZCT)
//
Managed Application (MA) registers with OCS 2007 SE via server application API
MA reads a text file of ZCT at the startup time
MA filters INVITE and BYE messages for further processing
Active Calls Count = 0
If received message is an INVITE
Look inside SDP
If SDP is for an audio or video call
Save Message Sequence Number
If _caller belongs to _sender_zone OR _callee belongs to _destination_zone AND Active Calls Count > MAX_CALLS_ALLOWED
Instruct OCS to deny the call // OCS Server API explains how to do this
Print “MAX CALL LIMIT EXCEEDED” in a text file
Send an IM to the Caller with the message
“Your call could not be completed, inadequate resources”
Else
Increment Active Calls Count
If received message is a BYE
If Message Sequence Number is known
Decrement Active Calls Count
