I was wondering if there was a programmatic way to intercept dialed digits from a device *before* they are processed by CUCM. Ideally what I'd like to do is get the dialed digits, do some interactive things with the caller, then allow the call to go through (with or without modifications). I considered CURRI, but the maximum timeout is 5 seconds. I need more than that. Also, I need to keep the CDR as prestine as possible or at least predictable. Thanks

You can accomplish this by 'intercepting' the initial call. I.e. digits dialed that would normally route to the orginal target are routed to your application CTI route point. The app can then paly messages, gather digits and otherwise make a decision to route the call further. By capturing the original called number, you can easily redirect the call to its original intended destination on 'green light.'
Downsides to this mechanism are fairly obvious: the app is 'in the way' of every call to this destination (scalability/impact,) and handling app failure scenarios may be tricky, in order to ensure some level of service.
