Hi Dimitri, 

hmm then describe what kind of headers you want to show your media server and hide from the client. 

You can normaly add headers (for example X- or P- headers) if traffic flows through your Kamailio. 

Maybe if you describe your goals and why you what this behavior, someone said "yes I did that with xyz module or solution ABC". 

Merry Christmas

i'm sorry. 

Of course i drop if $sndto(ip)==media_server. In this case "media_server" can see all stuff, but   "client" can see media_server headers too. I want "media_server" see all stuf, but "client"  kamailio_external_ip  only for the same session

Hi Dimitri,

You need to fill in the media_sever_ip that should see all the stuff. 

If you fill in one of the Topos running Kamailio ips it's disables Topos, that's true. 

Cheers

Hi, Karsten

It seems disable topos for full chain ( client -kamailio_external_ip - kamailio_internal_ip - media_server ) if i check $sndto(kamailio_internal_ip) and drop.

Hi Dimitri,

maybe there is a better way, but I used that for debugging purposes to disable topos to my inside ip, here 172.20.120.59 as example 

event_route[topos:msg-outgoing] {
	if($sndto(ip)=="172.20.120.59") {
		xlog("L_ERR", "NOT SEND TOPOS TO $sndto(ip)\n");
		drop;
	}
}

Hi all.

I have Kamailio with 2 addr: 

kamailio_external_ip - for client interconnect

kamailio_internal_ip - for local media server interconnect

Like this:

client - kamailio_external_ip - kamailio_internal_ip - media_server

"topos" module hide sip headers for both  "client" and "media_server" side.

Is it true: with topos i can't hide headers only for the "client" side  and show them for the  "media_server"? I want full header set visible for the "media_server", but  only kamailio_external_ip visible for the "client".
