Hi, Ehrny!

You don't need to use contexts in the onreply_route[], because thatroute is already ran in the context of the reply message.

Dear Răzvan,

… I’ve tried to add variable to onreply_route[1]

$var(upstream0) = $(<reply>hdr(Via)[0]{via.param,received});

xlog("upstream0  =  $var(upstream0) \n");

and in the log I get critical alert:

CRITICAL:tm:tm_pv_context_reply: no picked branch (-1) for a finalresponse

Hi Răzvan,

I gues so.

I’ve got      t_on_reply("1");       in the route

and at the end of the script there is:

onreply_route[1] {

force_send_socket(udp:10.197.26.170:5060);

}

But it doesn’t seem to change send_socket back to priv IP addr ((

Kind regards,

Ehrny

Hi, Ehrny!

Did you try setting the private socket on the reply?

    Dear Răzvan,

    Thanks again for the prompt help. I was able to change the headers
    as needed but I’m stuck with another problem(

    I’ve got opensips with two Ethernet adapters, eth1 as a private
    and another one eth0 as public.  Opensips works fine when the call
    is coming on the public eth0 and leaves opensips through the same
    public adapter. (All the GWs are behind that public eth0 instead
    of one ). The problem happens when the call comes in through the
    private eth1, please see the drawing in attachment.

    -sip1.  After I’ve got invite from provider on the private eth1 ,
    I send it through the public eth0.

    -sip2.  I use force_send_socket(udp:PUBLIC_IP:PORT) for the call
    to be able to pass through the opensips and come back from
    external GW (x.x.82.139). I also change SIP Request's URI and use
    uac_replace_to () to change these fields as needed.

    -sip4.  Opensips has got 180 Ringing from external GW (x.x.82.139)

    -sip5.  Opensips tries to send it back to originator
    (10.250.242.74) which is behind private NIC eth0 (10.197.26.170)

    the call can not be set up because I send reply from my public eth1

    2016-11-16 18:56:14      : x.x.80.43:5060 -> 10.250.242.74:5060

    I’m not sure if I do it right way because the packet (sip5) goes
    to 10.250.242.74 with the source ip of public eth0 and not the one
    it should pass through to be able to come back.

    What is the right way in my case to get the call through?

    Thank you for all of your help,

    Regards,

    Ehrny
