It's called connected line ID (it sends clid updates when things change). Asterisk supports it in recent versions (i believe 1.8 is sufficient) - your handsets may or may not (their method of transfer, and their ability to process the updates can affect it's workability). Given you've not mentioned your handsets, we cant make that judgement for you.
