With the ans. mach. approach, your phone rings, the recorded announcement 
begins, and then you type in your touch tone codes to turn on room monitoring.
Whatever/whoever you are trying to monitor (baby sitter, child home alone,
pet, burglar, etc.) hears the ans. mach. go off and then some touch tones, 
and thus may suspect being monitored.  The monitoring only lasts a few minutes,
and you are then queued to re-enter another monitor command or the line drops.

You may want to try the "infinity transmitter" (i.t.) approach.  The i.t. is
installed inside your phone, and gets it's juice from the phone (or from a
battery if one is using this device for illegal eavesdropping).  The i.t. 
intercepts your call BEFORE the phone rings.  You then type in your code,
and the phone mouthpiece becomes a live whole-room mic (very sensitive).
Available from your local neighborhood criminal type, or by mail order--
look in the back of Radio Electronics Magazine or Popular Electronics for those
companies that advertise wireless mics.  They sell infinity xmitters.
Most are kits that range from $45 to $100.  Assembled units slightly higher.
Check local laws before assembling anything like this.
