Question/recommendation re: Auto Replenishment feature

It's a great idea, and any reseller wanting to avoid a mass disruption in service should probably take advantage of it. However, in the interest of fraud protection...

Will the system send a SMS message immediately upon replenishment?
Will the system send an automated e-mail immediately upon replenishment?
Can we set something like a maximum replenishment within a 24 hour period?

I would hate to leave the office one Friday evening and return on Monday to find my CC has been charged to the limit with "replenishments" as someone goes crazy with international calling, etc.

An e-mail is O.K., SMS is better (and preferred), and a maximum is ideal.

(Sidenote - "replenishment" is spelled incorrectly on the Billing - Add Funds page... [Auto Replishment])

Just set a cap on minutes allowed :)

An SMS before a hard cap is hit is a great idea.

An SMS for a recharge, and a time limit to the next recharge is a great idea too.
