400 Bad Request-URI from very long Request URI

All,

 

Sorry for all the off the wall questions but working with the LyncIT has been a nightmare... In one of the TC's it sends a huge request URI which gets truncated and the NN4500 sends back a 400 Bad Request-URI.

 

Below is some of the signaling, any help would be greatly appreciated.
