Asterisk transfers calls at random?

I’m running the most recent 1.2 release at home with 1 POTS line which runs into a Linksys SPA-3102. OS is Slackware 12.0. Recently my family has started complaining that during a call, out of the blue they hear the “transfer” announcement, then the call disconnects. I do not believe that the # key is being pressed accidentally.

Any suggestions about how to troubleshoot this?


Change the transfer so its two digits and also enable debug in the logging
