[OpenSER-Users] T_replicate Bad Request Issue

Wed Jun 4 11:27:25 CEST 2008

Hi 

All I have the following setup

Openser Server A --> Uses Localhost MySQL Server

Openser Server B --> Uses ServerA MySQL server

Each server is in a different location.  Both servers share the same
database. I.e. in other words a user can successfully logon to either
server. Both servers have a similar configuration file. My problem at
hand is the following

User A and User C logon to Server A

User  B logs on to Server B

I need user A or user C to be able to call user B.

I am using t_replicate for this setup. The relevant config section is
found below:

if(src_ip == OTHERSERVER)

{

   xlog("L_INFO","PACKET FROM 9 PEER SERVER");

   save("location");

}else{

   xlog("L_INFO","NORMAL Packet");

   if(is_method("REGISTER")){

     if(!www_authorize("sero.test.net", "subscriber")){

                                    www_challenge("sero.ahwar.net",
"1");

                                    return;

      }

      save("location");

      t_replicate("sip:OTHERSERVER:5060");

      return;

}

I have looked at traces and it seems to me that if a user logs on to a
server t_replcicate forwards those register packets to the second
server. However the second server is not reponding to those register
packets it is replying with Bad Request replies
