Router system for SMS sending

[manuel-rubio]

It's important, with several providers, establish some rules for send SMS. Based on the usual rules we can provide:

• date/time rules
• destination prefix rules

Also we can add support to use a caller id or presentation id depending on the same rules.

An example of configuration could be:

{routes, [
    {time, {from, {0, 0, 0}}, {until, {6, 59, 59}},
        {prefixes, ["33", "34", "35", "36"]},
            {prov, lleida}
        }
    },
    {default, lleida}
]}.

The rules are recursive so, you can combine as much as you want. The format is:

• {time, {from, time()}, {until, time()}, rule()}
• {days, [0..6], rule()}
• {date, date(), rule()}
• {prefixes, [string()], rule()}
• {prov, provider()}
• {default, provider()}

When a full rule (with all of their children match, the rules is applied. Else the system check the next rule. default match with everything.
