[Serusers] rtpproxy and sethostport

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
