New subject: [Serusers] SER/PSTN Gateway conf

      My Record_Route and Loose section are the follow:
# -----------------------------------------------------------------
# Record Route Section
# -----------------------------------------------------------------
if (method!="REGISTER") {
record_route();
};
# -----------------------------------------------------------------
# Loose Route Section
# -----------------------------------------------------------------
if (loose_route()) {
    if (method=="INVITE") {
      if (!allow_trusted()) {
        if (!proxy_authorize("","subscriber")) {
          proxy_challenge("","0");
          break;
        } else if (!check_from()) {
          sl_send_reply("403", "Use From=ID");
          break;
        };
        consume_credentials();
      };
    };
route(1);
break;
};
As follow reported, SER Record Route INVITE original INVITE message, that lack
of 'Route:' header, and forward it to IP Phone. Why not for BYE? =_="
Thanks for support and big patience. ^_^

As far as I know and understand it seems that the
R-URI of the BYE mesg (1st line) which GW sends to SER is wrong.
I expected to see :
        BYE sip:user@SIP_Phone_IP_Address SIP/2.0
or the problem is that the 'Route:' header is missing from the BYE mesg
so it's not loose_routed.
Do you Record_Route the original INVITE ?
