Hello,

I ran out into some problem when implementing Call Forwarding feature using SER.

My test setup:

192.168.25.101 - XLite ---> INVITE UA(sip:444)

192.168.25.163 - ser; rewrites to Address of record of Asterisk (sip:1111 instead of sip:444)

192.168.25.169 - PBX Asterisk

 

As I see from log files, SER sends INVITE 2 times,

then Asterisk sends 3 times 200 status etc . until BYE is sent (here everything correct....)

Here is my configuration script:

==================================

route{

. . .
  
 record_route();

 #--rewrite URI  
 if (method=="INVITE"){ #--call forwarding
 setflag(1);
 route(1); #--cfw
 if(!isflagset(1)) {
  break;
 }

lookup("location")

...

};

 

route[1] {
 log(1, "forwarding\n");
 if (!if_activated("to")) {  
  #--continue regular call set up
  break;
 };
 if (!lookup_dn()){
  sl_send_reply("404","Not Found");
  resetflag(1); #--continue!
  break;
};

}

Here if_activated checks whether the feature was activated; lookup_dn() rewrites URI to new UA and call append_branch()

 

Any ideas what I am doing wrong?
 
 if (!t_relay()) {
  sl_reply_error();
 };

}

===========

 

Any help will be highly appreciated!!!
