Getting the text tone to keep ringing to wake me up - on call phone

[WPCentral Question]

I work 'on call' and need the phone to wake me up when I get a text by continuing ringing until I pick it up. On android there are loads of apps to do this but I cant find any way of doing it on the Nokia Lumia 920.

Short of flashing on the android os is there anyway of making this happen?

A simple solution is to have a pretty long and audible tone set for your sms or set it to a particular contact, this will work if you only use that particular phone for work otherwise it would get annoying pretty quick.
