[Asterisk-Users] how to show called name on calling polycom display

[Giorgio Incantalupo]

Hi,
we have an asterisk 1.2.1 box and 2 polycom SIP phones. We'd like to 
show the called name on the calling polycom display instead of his /her 
extensions as I do with the caller name on the called polycom.
Is it possible? If yes, how?

TIA
