I just commented on the other email you send, try with something like:
user_agent_header="X-Proxy: xyz"
Cheers,

Just found something interesting.
I just commented out the "user_agent_header" in the Global section and
restarted kamailio and now the REGISTER message seems to be completely
intact but now we have two occurrences of the User-Agent. I tried
doing the remove_hf("User-Agent) but it doesn't seem to have any effect.

I followed Daniel's instructions and made some progress but not
100% there yet.
-------[Global section]----------
user_agent_header=""
-------[Main Routing Logic]-------
# handle registrations
if (is_method("REGISTER"))
{
$avp(new_user_agent) = $ua;
}
route(REGISTRAR);
.
.
# Forward REGISTER to Freeswitch
route[REGFWD] {
if(!is_method("REGISTER"))
{
return;
}
route(DISPATCH);
$uac_req(method)="REGISTER";
$uac_req(ruri)=$du;
$uac_req(furi)=$fn + "<sip:" + $au + "@" + $ar +
">";
$uac_req(turi)=$tn + "<sip:" + $au + "@" + $ar +
">";
$uac_req(hdrs)="Contact: <sip:" + $au + "@"
+ $ar
+ ";fs_path=sip:"
+ $sel(cfg_get.kamailio.bindip)
+ ":" +
$sel(cfg_get.kamailio.bindport)
+ ">"
+ "\r\n";
if($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";
$uac_req(hdrs)= $uac_req(hdrs) + "User-Agent: " +
$avp(new_user_agent) + "\r\n";
uac_req_send();
exit;
}
#!endif
------------
Now the correct User-Agent appears in the REGISTER message but in
Freeswitch it shows as unknown.

Got some extra dots in there but not sure why they are there and
how they got there.
Any ideas? Anything I missed?

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
