I have implemented something similar with the Dial command. We had a
customer that required real-time call control where every 60s a new
request had to be made to reserve quota to allow the call to continue.
Part of that involved sending a Curl request from app_dial.c as soon
as the call answered and as soon as the call hungup. It works well and
is loosely coupled with Asterisk so that in the worst case the Curl
request times out after 2s and Asterisk could take alternative action
if necessary.

A nice side effect of this approach is that it's possible to get a
realtime display of calls in progress from the database rather than
having to use MAPI.

Ultimatley I think CEL is going to be the approach for tracking call
flow. Hopefully the CEL hooks will be two way so I don't have to keep
updating my real-time call control patch for each version of Asterisk
:-(.
