[Sipp-users] \r \n After service route header

[priyank luthra]

I have a registrar script which accepts a REGISTER and sends a 200 OK with
service route header.
The sip packet is having \r\n after the service-route header value:
Service-Route: <sip:servingproxy.com;lr>\r\n  Content-Length:    0

xml:
 <recv request="REGISTER" crlf="true">
  </recv>

    <send retrans="500">
    <![CDATA[

      SIP/2.0 200 OK
      [last_Via:]
      [last_From:]
      [last_To:];tag=[call_number]
      [last_Call-ID:]
      [last_CSeq:]
      [last_Contact];expires=900
      Service-Route: <sip:servingproxy.com;lr>
      Content-Length:[len]
   ]]>
  </send>


Can someone tell me why \r \n is inserted and what is its significance?
