Hi Bogdan , I have my server sip integrated with asterisk for voicemail and
meetme, adds to rtpproxy to solve my problems of nat with my remote clients,
the result was almost satisfactory some details to improve, the problem was
that after adding rtpproxy when my clients do not answer a call no longer
here jumps me to the voicemail only shows in the 488 Not Aceptable here..

UAC == NAT == internet ===wan === eth0 server sip/asterisk === eth1 === UAC
clients

asterisk port : 5070
sip proxy: 5060

I have tried to put the force_rtp_proxy ("", 192.168.1.64); , but it doesn't
always work me on he writes the sdp twice

onreply_route[1] {

if ((isflagset(5) || isbflagset(6)) && status=~"(183)|(2[0-9][0-9])"){
        force_rtp_proxy();
#       force_rtp_proxy("","192.168.1.64");
        append_hf("P-hint: onreply_route|force_rtp_proxy \r\n");

    }
        if (!search("^Content-Length:[ ]*0")) {

#    search_append('Contact:.*sip:[^>[:cntrl:]]*', ';nat=yes');

    if (isbflagset(6)) {
        append_hf("P-hint: Onreply-route - fixcontact \r\n");
        fix_nated_contact();
    }
 }
    exit;
}


my sip log:
