Quick question regarding this feature.

I added my cell phone as one of the simultaneous ring #. When I called home from my cell, it went to my cell phone voice mail admin prompt. Is there anyway to add rules to the simul ring to check for the caller id and determine whether to ring the # or not
e.g in the above case, my cell phone should not ring since the calling # is the same as 1 of the simul #.

Thanks
