Hi, last week I saw a cool feature in a PBX that seems me very useful
for hotel PBX's and so.
I typed 143 in my room phone to call a friend in that room. My
friend's name is... Bob? XD
When the call progress started I saw in my phone led "Calling Bob...".
Well, the only way we can do that in SIP is by giving the phone the
ability of search into a contacts addressbook for the typed number and
retrieve the extra info (as DisplayName) using any other protocol
(http, ldap...). This way is not very nice (always) since the phone
needs inteligence to access to the addressbook resource using other
non SIP protocol (and note each phone model implements different ways
to access a remote addressbook, some of them using vendor private
protocols or formats).
You're looking for connected line identity. With that you can send
information
about which phone that is ringing, and which answers.
Some people use remote-party-ID for this with party=called.
RFC 4916 is the recommended way moving forward, but not implemented
in many places.
I've done some research for Asterisk regarding this, which is
available here:

Hope this helps and inspires you!
