Perhaps you can get it with adding User-Agent header to $uac_req(hdrs):
$uac_req(hdrs)= $uac_req(hdrs) + "User-Agent: " + $ua + "\r\n";
And sent the global parameter:
user_agent_header=""
But then no local generated request has user agent, which probably is ok for you.
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 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?

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#event_route BR, Sammy On Tue, Oct 7, 2014 at 11:20 AM, Errol Samuels <ewsamuels@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].
