[Serusers] rtpproxy and sethostport

[radan]

Hi all !
How can I use rtpproxy if i want redirect connection
from my client behind NAT to another user registered on another sip server
I can't use SRV records

# redirection to another sip server
if (uri=~"sip:1([0-9])*@.*") {
  setflag(1);
  strip(1);
  if (nat_uac_test("3")) {
  fix_nated_sdp("1");
  force_rport();
  fix_nated_contact();
  force_rtp_proxy();
  };
         record_route();
         sethostport("another.sip.server.pl:5060");
if (!t_relay()) {
       sl_reply_error();
  };

break;

        t_relay();
  };

The connection is estabilished fine but I don't hear

Thanks
Andrzej
