With SIPServer, do you only get TLib events, and no SIP events?
Data Collector is configured as a ThirdParty Application and is a client of the SIP server thus receiving the TLib events over the network. The events in that stream are processed and placed in storage. Data Collector also has a designated folder that it monitors and a SIP Server log is placed in that folder. Data Collector processes that file to gather all SIP messaging events, then places the file in storage, then deletes that log file from the folder. It all gets tied together by the unique session IDs.
