I have got several calls recently with my other UC expert friend eager to know “How Can identify Lync caller location“. There are several option to trace it including wire shark, Fiddler and Netmon live traces. But instead of siting to do live trace you can do it offline with the help of lync CDR monitoring console.
Of course you must have it, no choice 🙂 !!
Its pretty simple, login to your Lync monitoring console and search with Caller “User URI prefix”. Click on the audio call which you want and jump directly into “Media Line (Main Audio)” section.
I have two example as below
a)Caller is in outside/internet and callee is in corporate network
b)Caller and callee both is in corporate network
Hope it will help you 🙂
