Telephone Baby Monitors are quickly becoming a must have item in the baby monitoring arena.  The concept is relatively simple, but ingenious in design.

These monitors are designed for occassions where, for example, your baby is fast asleep in your hotel room.  You might like to go to the restaurant to have a meal.  It may be that your normal baby monitor might not be able to get a signal from the restaurant to your room.  These monitors (depending on model) can be set to either call through the hotel landline or connect to a mobile phone and call if your baby cries.

They can also act as a fly on the wall if you have gone out but would like to call home to hear your baby sleeping peacefully, or make sure your babysitter isn't having a party.

The monitors are normally highly portable, allowing you to take them on holiday or move them from one room to another.
