Maybe somebody else has a better pattern, but for now, I've implemented a
middleware to fetch ics calendar and store that in folders served by a
Nginx.
Asterisk retrieves ical directly on localhost.

Two advantages:
1. Asterisk don't waste CPU time to retrieve data.
2. If the calendar source is down, it's invisible from Asterisk.

However, the main issue is that I didn't find a way to force Asterisk to
purge its cache and reload a specific calendar.
I play with timeouts to avoid to be too much in delay with the latest
version available of ical.

Have a nice day.
