[asterisk-users] Is it possible to set a timeout when querying a calendar ?
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 -------------- next part -------------- An HTML attachment was scrubbed...

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.
