HISTORY ( Dropped ) message in URS logs

URS 8.1.4 SipServer 8.1.1

I noticed many calls that show the message HISTORY ( Dropped ) in the logs when they are already routed to an Agent (using WDE). Where should I check, for troubleshooting?

Why you say it was routed to an agent?

Hi Cav. The URS selects the target and tries to route there, I see urs calling a strategy loaded on the extensions dn ringing state, router tries to connect call and agent (add DN sipserver [EXTENSION] <[EXTENSION]@[SWITCHNAME]>), then it drops it with that message. On his side, the agent doesn't see anything, nor ringing. Same agents work with other calls, so doesn't look as an agent issue.

======== DN Information =======
Number [EXTENSIONDNNUMBER]
Access [EXTENSIONDNNUMBER]
Agent [AGENTID]
Place [EXTENSIONDNNUMBER]
Login [AGENTID]
Switch [SWITCHNAME]
Type 1
===============================
============== Target Information =================
Name    < [AGENTGROUPNAME >
Location < [STATSERVERNAME] >
Type    < GA >
STATE MAPPING -  < ##state >:
Stat Value: DN info OK
Modelling  : NA
===================================================

Check Sip server. I do see it as a lack of communication between agent and Sip server
TLib started to try something, but didn't reach it's destination.
