I am having some trouble with an asterisk install. I am not even certain that what I want to accomplish is possible.
I want to leverage asterisk queues to provide call center functionality in my Cisco Call Manager environment, rather than pay the outrageous agent license fees for cisco’s contact center product. I have a sip trunk built and it works well, I can pass calls to asterisk from my cisco phone and get calls back. The problem is that asterisk has no idea what the handset status is, so when a call comes into the queue i am using, it sends it to phones that are already in use. From quite a bit of searching on the internet, it seems that it is possible to send and receive this status, possibly by using subscriptions and hints. Unfortunately, I am not as knowledgable about this as I would like to be, so while I can recognize the terminology, I am not finding much documentation on the actual implementation of this.
Is what I am trying to do possible, and if so, how do I go about adding the necessary configuration?
