asterisk users - May 2007 - Display Caller ID of called party

Not sure if this can be done or not, but I can't seem to find it
anywhere on the Wiki. When dialing interoffice with Asterisk 1.4.2, I
would like to have the caller id of the person I am dialing displayed
and not the number I just dialed. Is this possible? So, if extension
4023 is John Doe, and I dial 4023, my display should read John Doe and
not 4023. I am using a Polycom 501 by the way in case that matters.

 

Any ideas?

Kevin,

It seems to me that what you are really talking about is manipulating the 
display features of the phone.  Caller ID is unlikely to have this effect
as the phone does not consider the From: URI in the SIP header unless the
call is of an incoming nature.

The solution to this is bound to be proprietary to the phone in some way
or another--if there is one.  I just wanted to point out that the mechanism
for its delivery would almost certainly not be caller ID.

Of course, you COULD always set your dial plan in such a way that it never
actually completes the outbound call leg, but instead hangs up, and then
dials it, and rings you back (with the caller ID of the intended
"incoming"
leg).

On a Grandstream GXP-2000, this happens when the dialed number is in the XML
phonebook that the phone sucks down from my provisioning server.  It might
work the same on the Polycom units.  Of course, you need to have some
process in place to keep the phonebook file up to date.

To do it in a generic way where the name is looked up by * and sent back to
your phone for display as part of the 100 Trying or 180 Ringing responses,
is an entirely different matter.  I suspect that the end-user experience
would vary wildly based on the equipment each user was using.  If this is
possible, I'm sure people more knowledgeable than me will chirp in.

The phonebook route might be the quickest bang for your buck though.  If I
recall from testing Polycom phones, you can have a central phonebook shared
by all phones and a per-phone phonebook that is uploaded by the phone to
your TFTP server so that even when re-provisioning from factory reset,
nothing is lost.  I didn't get far enough in the evaluation to set up a
provisionin server of my own.  The evaluation died in committee when an exec
reported that she "didn't like the small buttons" on the IP430.

The polycom will display the name of the person you are calling if it  
receives it in the remote-party-ID.  This is how it works with  
Broadworks.
