Thank You David.

What is a title name / tag name "some scripts posted here ob the forums that promise that functionality" ?

Could You give the link ?

Thanks for Your help.

So, there is no any tips how to configure on CUCM to make IP Phone Caller internal/external display automatic import/uisng first and last name on AD(LDAP) ?

Susanto,

Not any more than we have already explained.  The call manager is not able to perform dynamic name resolution based on call setup information.  Other applications can be inserted into the mix to provide this.  For calls from the PSTN, you can use something similar to the TCL script that was referenced earlier or you can look at a 3rd party app that was also listed.  The TCL script would only appy to calls from Off Net callers to On Net (i.e. IP phone) users.  To deal with Station-to-Station calls on net, you would need to pass every call through a 3rd party app to perform the dynamic resolution.  That isn't really scalable.  Now, I am assuming Cisco IP phones.

Some client stations may have additional functionality that I am not aware of but then you are into a whole different world of compatibility testing.

HTH.

Running TCL scripts on gateways, while doable, is not always scalable(depending on how big the environment is and how many PSTN gatewaysthere) and running every call thru a 3rd-party application isn'tscalable and will impact performance - possibly quite noticeably.

Actually, in these days of fast computing, the impact of running a TCL script for every call, triggering a database query (actually a lightweight one as the name LDAP suggests), is absolutely negligible and does not negatively affects anything in no case. Consider for example, massive voice access server like AS5400 that have terminates hundreds of calls simultaneously, do not have any problem in doing that (for IVR, pre-paid, etc), they also run RADIUS queries, and everything works smothless in voip and databases since 10 years now.

Imagine if I called you and was listening to dial tone or ring backwhile CUCM sent my call data to a 3rd-party app that had to then domultiple DB queries and send info back to CUCM before the call camethrough.

Yes you are imagining correctly, the whole process takes 2 or 3 milliseconds, in the meanwhile the call is progressing anyway, and the script is smart enough to never block on query failure, it will simply display "name unknown" instead.

So, if we are not worried about running java-based scripting on CUE on a slow clock Pentium platform, why should we worried for few lines of TCL talking the typical high-performance servers of an enterprise.

Thanks for Your information.
