I think a missed call package is a decent idea.


I've been pondering something similar in the scope of residential primary line service definition in another SDO, and one of the approaches that has been suggested is the use of a "network event package" that could do things like tell a subscriber:


* A call was sent to your AOR but answered at another Contact:

* A call was sent to your AOR, but since you have diverted all calls to voice-mail, it was sent there.

* A call was sent to your AOR as a result of a forwarding operation applied to a transferred call in a partner network, was rejected from your voice mail server for lack of a compatible codec, and has been diverted to a small pub in East Anglia that we thought you might be at.

* A call was sent to you AOR, and forked to your contacts, one of which replied with a "busy everywhere" response causing us to reject the call. Perhaps you should check into it.

That is to say, perhaps such a package could reflect both 1) processing decisions made by a serving proxy for an AOR in response to a request, 2) history information contained in that request, especially if such information is used in the processing of the request, and 3) history information gleaned from processing of the request in other nodes on alternate paths "downstream" from the proxy.

So in addition to being able to give a you a missed call summary (ala the old Teltier 2g application by that name), this package could also issue the logical equivalent of the "splash rings" that Class 5 switches send when they've diverted a call away from a subscriber line as a result of call forwarding. Or it could tell employee Bob in the call center that fellow employee Alice just took a call, and that she's taken the last three calls for the call center, and perhaps he should finish his tea and get back to work before Alice comes looking for him with a tire-iron in hand. Seems like a useful bit, eh?

Dean, I am in at least partial agreement with where you are going. But note that it isn't this package that *does* all those things. It is applications in the UA that use the package to help them do these things.
