mysterious phone calls

Answered

every Saturday at precisely 7:13 pm, there is a phone call made from my home land line number.  The call lasts about 10seconds, for which I am charged 35 cents per call. This is a bit curious, as it hasn't been plugged into the wall for about a month.  I use my mobile for phone calls and only use my land line for broadband connection.  

 

does anyone know what these calls are?  On the telstra bill they are listed as a "13" number.

Do you have a Back to Base Alarm?  If so, that is what it is.

Never be afraid to back yourself when trying new things, just always make sure you have 3 escape routes if things go wrong.
