free caller id tool for external call?

Unanswered Question
Jul 8th, 2007


One of our client wants to know who is maliciously calling her but everytime the phone (7940G) rings, it only displayed "unknown number" or "external call". When I look at the CDR, there's no number for external call only calls from internal which of course I don't need. I also used the CAR's Malicious Call Details but no results. Can someone suggest a free tool or plugin for this?

We got CCM 4.1(3)sr3a.



I have this problem too.

If the phone shows external call, then the CLID was not received by CM. You might want to contact your Telco to know why they did not fwd the caller ID.
