Called Id

Is it possible to display the name of the Called extension?
So it shows:
To: 101

I’m isung free pbx ver 2.1.1 and Polycom phones.

This seems possible with ADSI and ADSI-aware phones. Refer to Asteriskguru (http://www.asteriskguru.org/tutorials/adsi_conf.html).

Sorry, I’m not offering an answer to your question.
