CUPC 8 Trigger Directory Lookup for External Calls

Hi,

We have a setup with UC 8.0, CUPS 8.0 and CUPC 8.0.  We are facing an issue whereby directory lookup is trigger wrongly of external calls.  The internal users are on a 3 digits extension, eg user John on DN 456.  If an external call with a caller id ending with 456 (eg 9123456)  call to any one in the office, the CUPC shows up as John from 456 calling.  However, on the physical phone it is still showing the correct caller id of 9123456.

  We did not setup andy Directory Lookup rule on CUCM.

Anyone have any idea where I should look at?

Thanks!

Daniel

I would think that either cucm is transforming the calling number or dial rules are getting applied.

To check this simply take a sniffer trace while in soft phone mode:

- check the sip invite to see what the calling number is that is offered by cucm

- check for ldap requests for lookups in the directory

Make sure you are using cupc 8.0(3), with 8.0(2) there was an issue that the client was mixing up application dial rules and directory lookup rules.
