The basic problem of any call routing is that the server has to be able to decide if a call center client can receive a call or not. The simplest cause for not being able to receive a call is that the client is occupied with an existing conversation, but there can be other cases too.

The call center agent needs to be able to set their presence information to notify the server if they are able to receive a call. The presence information can specify if the agent is not at the computer at the precise moment and therefore they cannot answer a call.

It can be easily see that setting the presence information is a basic problem in call routing process.
