Record-route header is inserted by a proxy
to make sure any future requests for the same dialog will go through it. This
can be used for different purposes and one of them is billing.

RFC 3655 question for Record-Route? 





   




 
  
  Hello,


  


  So record-route is just inserted for billing purpose. Is that header not
  necessary for the proxy to know about the source/destination for routing SIP
  messages?


  


  Thanks for your response,


  KL

  Hi, 


  
  
    


  
  
  The SIP proxy just routes the SIP messages, so when
  the SIP proxy receives a message, depending on its role, it can decide if it
  wants to insert the record-route to header field. If it inserts the
  record-route,  the following SIP messages will be passed through it. 


  
  
  In this case, may be the Proxy2 is not used for
  billing, so it don't care about the BYE message. Thus it does not insert
  record-route here.

    Hello,


    


    RFC 3665, last line of page 45 mentions that 


    (Also note that Proxy 2 does not Record-Route in this call flow.)


    


    


I am not following why the Proxy2 doesnot Record-Route here. 


Also, how BOB reaches to the Proxy if RR is not included in the INVITE?


    


Thanks,
