Input on a HMR to change a 400 Bad Request to a 414 Request URI Too Long

The other thread where I got some input on craziness the LyncIT or Lync Interoperability Tool is sending for a test case.

 

Original thread

 

basically LyncIT is sending a call with an enormous Request URI and they say I should be responding with a 414 Request URI Too Long rather than the 400 Bad Request I am sending....

 

Example of the Request URI below and a HMR, wondring if there is a better way to do this HMR.

 

 

370705	30710.433506000	aaa.bbb.ccc.ddd	aaa.bbb.ccc.ddd	SIP/SDP	1374	Request: INVITE sip:+1NPANXXXXXX@themicrosoftlyncserverinteroperabilitytoolthemicrosoftlyncserverinteroperabilitytoolthemicrosoftlyncserverinteroperabilitytoolthemicrosoftlyncserverinteroperabilitytoolthemicrosoftlyncserverinteroperabilitytoolthemicrosoftlyncserverinteroperabilitytoolmicrosoft.com;ext=12345;user=phone | , with session description

The <wbr> does not exist in the URI, it is being added in from the code syntax highlighter.
