However, there is niggling pain in the neck issue where the user's User-Agent shows in Freeswitch as kamailio (4.0.6 (x86_64/linux)) instead of the user's Real User-Agent I am trying to get Kamailio to pass the real User-Agent of the user without success. I am able to set a static User-Agent by doing this in the global section. *user_agent_header = "User-Agent: We love beer";* However, I am unable to set it dynamically for example: *user_agent_header = "User-Agent: " + $ua; * *have you tried ... * *user_agent_header = "User-Agent: $ua"; ? * With is one Kamailio doesn't even start so my syntax is probably wrong. I also tried playing around with the textops module so I have ran out of ideas Any ideas?

You have to use event_route[tm:local-request] if you use uac module to send out new REGISTER.

Hi Sammy, Thanks for your response and the clarification. What I am actually trying to do is to pass the real User-Agent info for each device as the Registration is fowarded to Freeswitch so using your code as an example instead of hardcoding the custom "User-Agent: My Server SIP Server" which will show up in Freeswitch for ALL users I want to do something like user_agent_header="User-Agent: $ua" ; Where $ua as you are aware would be the Real User-Agent of the actual user who registration is being forwarded to Freeswitch. if($sel(contact.expires) != $null) $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $sel(contact.expires) + "\r\n"; else $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $hdr(Expires) + "\r\n"; event_route [tm:local-request] { # Handle locally generated requests xlog("L_INFO", "Routing locally generated $rm to <$ru> + Modify the User-Agent Header \n"); user_agent_header="User-Agent: $ua" ; } uac_req_send(); exit; I tried to add that code just before the "uac_req_send()" but I get errors when starting Kamailio, Is this compatible with Kamailio 4.0.6? 0(44073) : <core> [cfg.y:3567]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 1034, column 2-12: syntax error 0(44073) : <core> [cfg.y:3567]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 1034, column 2-12: bad command 0(44073) : <core> [cfg.y:3567]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 1034, column 2-12: bad command 0(44073) : <core> [cfg.y:3570]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 1034, column 14: bad command 0(44073) : <core> [cfg.y:3567]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 1034, column 15-30: bad command 0(44073) : <core> [cfg.y:3570]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 1034, column 31: bad command 0(44073) : <core> [cfg.y:3570]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 1034, column 33: bad command regards, Errol On Tue, Oct 7, 2014 at 9:28 PM, SamyGo &lt;govoiper(a)gmail.com <mailto:govoiper@gmail.com>> wrote: Hey Errol, What I get from Daniel's email is that you only need to add this route in your script and it will trigger itself automatically when "uac_req_send()" function is executed. event_route [tm:local-request] { # Handle locally generated requests xlog("L_INFO", "Routing locally generated $rm to <$ru> + Modify the User-Agent Header \n"); user_agent_header="User-Agent: My Super SIP Server" ; } Reference: http://www.kamailio.org/wiki/cookbooks/4.1.x/core?s[]=event&s[]=route#e… BR, Sammy On Tue, Oct 7, 2014 at 11:20 AM, Errol Samuels &lt;ewsamuels(a)gmail.com <mailto:ewsamuels@gmail.com>> wrote: Thanks for your input Daniel but pardon my ignorance as I am not 100% clear where I need to add that event_route[tm:local-request].

There are still ways to use event_route[tm:local-request] to set a custom user agent header, but would require something like: - add $us in $uac_req(hdrs) as X-UA header - in event_route[tm:local-request], remove User-Agent and X-UA headers and add again User-Agent taking the value from X-UA Cheers, Daniel

HI Daniel, Thanks for that. In my case I would need to use something like: user_agent_header = "X-Proxy: $ua"

since we don't what to hardcode a specific value which would affect every device that is registering but rather $ua which would set the real UA of the device that is registering at that time. Does that make sense? regards, Errol On Thu, Oct 9, 2014 at 12:09 PM, Daniel-Constantin Mierla &lt;miconda(a)gmail.com <mailto:miconda@gmail.com>> wrote: On 08/10/14 19:25, Errol Samuels wrote: Apparently by setting an empty user-agent header value in kamailio config file results in an empty line in headers, which means end of headers.

A solution for now will be to use: user_agent_header = "X-Proxy: abc" Or, in other words, set the value of the parameter to something that doesn't include User-Agent: as header name.
