This bit of dialplan simply set the name part of the caller ID and then call our phone, which in our example is SIP/abcdef. Note that we dial the phone directly instead of jumping into the standard XiVO dialplan, because we don't want the voicemail of the user to answer the call if it isn't answered in time.
Now that this is done, we load the dialplan we just added previously with the following command:
asterisk -rx "dialplan reload"
Next step before writing our cron job is to test out the command that will make our automatic call origination works. This use the "channel originate" command available from the asterisk 1.8 CLI. Let's try it out:
asterisk -rx "channel originate Local/s@daily-scrum exten 1051"
This makes our SIP/abcdef phone ring, showing that "Daily Scrum" is calling us, and once we answer the call, we are bridged into our conference room at extension 1051.
So we reach the last step on our journey; writing our cron job. Let's create a file at /etc/cron.d/daily-scrum and write the following line:
0 9 * * 1-5 root /usr/sbin/asterisk -rx "channel originate Local/s@daily-scrum exten 1051"
This cron job will launch our asterisk command every day of the week at 9:00 AM.
So that's it. Starting from this setup, it's possible to do other things. For example, paging and autoanswering a group of phones and then playing a sound file is just a bit of custom dialplan away.
Note that to make this work in XiVO 1.1, the dialplan shown here need to be modified (the "same" syntax is not supported in asterisk 1.4) and the "channel originate" command be replaced by "originate".
