Windows Phone 8 now supports custom text tones so you can select custom text tone (SMS) for each phone number. This works great but I have a problem because I would like to select a custom text tone for receiving fire alerts (like pager), but the problem is that sender of this messages is not a phone number but a text entry (instead of for example 0028631234523, sender is GZTrbovlje). I have tried to save this as a contact and then add a custom text tone, but it doesn't work, because it is not a phone number. Any idea how to solve this?
I would like to have this configured because I would like to have a very loud text tone fort his messages. Andoid has a FireAlert app but there is no app like this for Windows Phone so this would be a good workaround.
