Is there a way to match a portion of text in the message body exclusively from the sender match? When I get SMS through my provider's email to SMS system, it comes through with the sender as a random number. However, the body of the texts that I would want Klaxon to fire on always have a certain string in them. Right now I have Klaxon firing on everything all day and night so I won't miss a critical situation at work. When it is just friends or family texting, I don't need the loud, obnoxious, repeating alert I want for those. Any help would be greatly appreciated!
