User-Agent header and Server header not sent in the requests/responses

[logslie]

Description

When configuring as a global configuration the following parameters:

user_agent_header="User-Agent: foobar-1.0.0"
server_header="Server: foobar-1.0.0"

I expected to have in every responses the Server header and in every requests the User-Agent header. But I'm only see the Server header in the first 100 response and the User Agent header is never sent in the responses.

Log Messages

I don't have any error message in the log.

SIP Traffic

• First response to an INVITE with Server header.
  

• First resquest without User-Agent header:
  

• Second response without Server header:
  

Additional Information

• Kamailio Version - output of kamailio -v

kamailio-4.4.5

• Operating System:

Linux test200 2.6.32-642.15.1.el6.x86_64 #1 SMP Fri Feb 24 14:31:22 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Is there something that I'm doing wrong?

Thanks

Those headers are added by kamailio only when it is the origin of the request (adding user-agent) or the response (adding server). If kamailio is forwarding the request or response, it doesn't add any of these headers.

You can add them using append_hf(...) in the request_route{} or reply_route{}.

I am going to close this issue, if you need to seek further clarifications, use the sr-users@lists.kamailio.org for discussions.
