LEM SMS Alerting


I am wondering if anyone has been able to configure an LEM rule to alert them via SMS? I recall pre 5.7 that you could call a script, but cannot see that option any more in 5.7.0. I suspect it is achievable by sending an email to an SMS Service which converts email to SMS, or use the correct email address for the mobile provider e.g. phonenumber@provider.domain where some mobile providers can send an email to a phone as SMS/MMS.
