[SR-Users] Kamailio LCR Multiple choices

[Ali Taher]

Hello,

 

I'm using LCR module to send multiple choices.

Everything works fine so far , yet I have a problem that  last gateway comes
first, then gateways are ordered correctly.

 

Below is correct sorting of gateways:

First gateway : 192.168.26.4

Second gateway: 192.168.26.1

Third gateway : 192.168.26.6

 

Below is Invite response I'm getting, as you can see 192.168.26.6 (last
gateway) is included as the first gateway , then 192.168.26.4 (first
gateway) comes next. 

 

Via: SIP/2.0/UDP
192.168.26.3:37066;branch=z9hG4bK-d8754z-885c37410729cc3b-1---d8754z-;rport=
37066;received=192.168.26.3

From: "5000"<sip:5000 at 192.168.110.181>;tag=aa37be29

CSeq: 1 INVITE

Below is routing block I'm using :

 

if (is_method("INVITE"))

                {              

                  if (!load_gws(1, $rU, $fu)) 

                                                                  {

                  sl_send_reply("502", "Unable to load Gateways");

                  exit; 

                                                                  }

                  else while(next_gw()) 

                                                                  {

                  append_branch(); 

                                                                  }

                  sl_send_reply("300","Multiple Choices");

                  exit;                                     

                }

 

 

Appreciate your help.

 

Regards,

Ali
