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

The OCCAS server configured with below SIP parameters:
enable-local-dispatch, server-header , server-header-value,
globally-routable-uri
Enable local dispatch
Enable a server optimization that helps avoid unnecessary network traffic when
sending and forwarding messages.More Info...
Default SIP Server Behavior:
proxy ua
The default behavior of the WebLogic Communications Server instance if the
server cannot match an incoming SIP request to a deployed SIP Servlet, or if
the matching Servlet has been invalidated or timed out.More Info...
Server Header Insertion:
none request response all
Specifies the conditions for inserting a Server header into SIP messages.More
Info...
Server Header Value:
The value of the Server header inserted into SIP messages.More Info...
Default Form for Header Insertion:
compact long force compact force long
Specifies how the server applies rules for compacting SIP message headers.More
Info...
Enable DNS Server Lookup
Specifies whether the server performs DNS lookup.More Info...
Enable Call State Cache
Specifies whether engines cache a portion of the call state data locally.More
Info...
Enable Contact Header For Non-Reliable Provisional(1xx) Response
Specifies whether the server puts Contact Header in non-reliable
provisonal(1xx) response having To tag.More Info...
Globally Routable URI:
A Globally-Routable User Agent URI (GRUU) that WebLogic Communications Server
automatically inserts into Contact and Route-Set headers when communicating
with network elements.More Info...
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
