 Posted: Tue Jun 21, 2016 5:18 am Post subject: [asterisk-users] Is it possible to set a timeout when queryi |
 |
|
Hello,
Asterisk offers several ways to query an external calendar.
I'm wondering what could happen if an external calendar was down or very slow to respond.
Looking at wiki.asterisk.org, I didn't find any timeout parameter in calendar functions, nor in calendar.conf (but I'm not too sure for the later case) ?
What would you suggest to protect your dialplan from a mis-behaving external calendar ?
Best regards |

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.
