Is it possible and if so, how do we set up the system so that when a number is dialed internally (by extension) the Name of the person we are calling displays on the phone instead of the extension. (Currently our display shows the following:
To: 1234
1234
I would like to see
To: John Doe
1234
Thanks for any assistance 
Wow, exactly same feature request as forums.digium.com/viewtopic.php?t=14962 Does someone know of a non-proprietary VoIP system that has this?
so what you do not know who u r calling???
Really what is the point?
I have never seen (or maybe never noticed) any PBX ever doing this.
I don’t think this is something that a PBX would handle. The phones can, however, if they have access to the information. Our Aastra phones have this feature because the phones download the company directory from a TFTP server. So when you call 210 the phone looks it up in the directory and displays the name.
