Listening In

[danally]

I tested my alarm and had it call another phone line in my house. The X10 called my phone but I could not listen in.  I pushed every button on my phone but it would not stop the outgoing X10 message.  I could not listen in.  Please help! Thanks!

Try pressing 0 to listen in, if not you probably have a defective unit a pretty common occurrence around here!
