    Need Information On SIP Contact Header parameters wlsscid and sipappsession

    714625
      Hi



      We are using OCCAS Web Logic server to deploy our application. The content header information has fields wlsscid & sipappsessionid which are coming as default. Want to understand more how & when these fields are getting populated and their significance. Please find the message snippet below



      Via: SIP/2.0/TCP 10.68.20.101:5067;*wlsscid=d09c87074527*;branch=z9hG4bK6f882d53b3f7e95ef23452ec3412ab76;received=10.68.20.104

      Via: SIP/2.0/UDP 10.48.27.197:5090;branch=z9hG4bK_IMSCA0500514.000_51c3d4c797ac2666f8b9fddc1bd7534c01;lskpmc=S05

      Via: SIP/2.0/TCP 10.48.27.197:5070;branch=z9hG4bK_IMSCA0500514.000_32e277815bbabf5de92486514f1e4ad3;lskpmc=P07

      Via: SIP/2.0/UDP 10.68.20.101:5168;branch=z9hG4bKnashds8

      Record-Route: <sip:10.68.20.101:5067;*wlsscid=d09c87074527;lr;sipappsessionid=app-5u4nn0gjyl4j*;wlssrrd=out>

      Record-Route: <sip:isc@scscf.ims2.mlab:5090;routing_id=775a4689c391524586728ff1f57883f6;lskpmc=S05;lr;interface=bcc;tid=51c3d4c797ac2666f8b9fddc1bd7534c01>

      Record-Route: sip:pcscf.ims2.mlab:5070;routing_id=pcscf_a_side;lskpmc=P07;lr



      The OCCAS server configured with below SIP parameters:

      enable-local-dispatch- false
      server-header- none
      server-header-value-WebLogic SIP Server
      globally-routable-uri -false
      Enable Contact Header For Non-Reliable Provisional(1xx) Response-false
      Default Form for Header Insertion -long


      If I set the sip parameter “use-header-form” i.e “Default Form for Header Insertion” with option “compact” will it reduce the size of the header?



      Could anyone provide some information on removal of above fields (wlsscid & sipappsessionid) to overcome some sizelimitations which I am facing when sending this request to other applications and some information regarding these parameters.



      Thanks in Advance,

      Kranthi
