How to validate so that only one out of three telephone numbers is required using jQuery validation plug-in 1.7?

How to validate so that only one out of three telephone numbers is required using jQuery validation plug-in 1.7?

Hi,

I have a user registration form with some fields and among them I have contact information which primarily contains three input text type fields 

1. Home Telephone 
2. Business Telephone. 
3. Cell no

I have error div defined for each control where I place the error. This is defined using the errorplacement option of the jquery plugin syntax.

My requirement is that, only one out of the three is required and if filled it should be valid irrespective of the other two being entered and error messages from other telephone input should be removed

Regards,
Thoef
