Sorry about the wording in my post, its a little off. What I meant to say was that I had to edit the column in the database table to change the character limit value to something higher than 30. The issue appears to be that digium phones are setup to strip anything in <> which used to be just
<Alert Info: foo>, since
<http://127.0.0.1>; info=CUSTOMINFO is the new value it was causing issues with the alert. The problem now is that the new alert info is longer than 30 characters, so if you need to update the column to more than 30 (I set mine to 100) its pretty easy from the cli:
Issue fwconsole m which will drop you into the mariadb/mysql cli connecting to the asterisk database:
[root@pbx ~]# fwconsole m
Increase the length of the column alertinfo in the digium_phones_alerts table as needed (change 100 to whatever value you need):
MariaDB [asterisk]> ALTER TABLE digium_phones_alerts MODIFY alertinfo VARCHAR(100);
That should be it. I just wish there was a ‘official’ fix for this.
