I am working with a client that detected many calls with destination of a specific country (Venezuela in this case). But when I check the CDR records, <SPAN>most calls has the "CallingPartyNumber" field empty. <BR />I've been reviewing the meaning of this field being empty, and what I found defines: "For server calls, where Unified Communications Manager originates a half call without a calling party, this field can remain empty." However, I do not understand these types of calls yet. <BR />When I review them at the RTMT level, I see that there is a negotiation between an IP of an E1 and one of the client's Subscribers. <BR /><BR />Another field that I see is the “finalcalledPartyUnicodeLoginUserID” field, which appears with the value “\” in all these calls. And I do not understand what this value means. <BR />Someone could&nbsp; help me with these queries to understand these calls? <BR /><BR /><BR /></SPAN></P> <P><SPAN>Thanks in advance!!!</SPAN></P> Thu, 01 Sep 2022 19:50:04 GMT Lucas_15 2022-09-01T19:50:04Z https://community.cisco.com/t5/collaboration-applications/cdr-report-with-calling-dn-in-blank/m-p/4679955#M48070 <P>Hello all!</P> <P>I need your help for try to understand the beahivour of some calls.
