The way we handle at my work this is to include a special string in the alert name (e.g.$SMS$, #TEXT# etc.) and have an email rule set up to forward that via SMS to the relevant area. You will need access to some form of SMS gateway or product.
Currently, we can only send out messages as SMTP. SMS is not supported. However, some carriers can convert the message if sent to something like <number>@att.com. You'd have to check with your carrier to make sure they support this.
