Contexts can be included in other contexts. All included contexts are listed within a single block.

context default {
    includes {
        local;
        longdistance;
        international;
    }
}

Time-limited inclusions can be specified, as in extensions.conf format, with the fields described in the wiki page Asterisk cmd GotoIfTime.

context default {
    includes {
        local;
        longdistance|16:00-23:59|mon-fri||;
        international;
    }
}
