Hello,

if you use forward() then the retransmission is not from kamailio - forward() does stateless forwarding.

The dispatcher module readme in devel branch has a better example, maybe it helps you: http://kamailio.org/docs/modules/devel/modules_k/dispatcher.html#id2513148

Cheers, Daniel

Hi all,

I'm using kamailio dispatcher module between the OpenIMSCore and sailfin. Normally, without the dispatcher, all works fine. From the IMS Bench I can see that there are many successful call, but when I use the dispatcher module I'm having a lot of retransmission in the first part of the INVITE protocol. I'm using the default configuration file:

# ----------------- setting module-specific parameters --------------- # -- dispatcher params -- modparam("dispatcher", "list_file", "../etc/dispatcher.list") # modparam("dispatcher", "force_dst", 1) route{ if ( !mf_process_maxfwd_header("10") ) { sl_send_reply("483","To Many Hops"); drop(); }; ds_select_dst("1", "0"); forward(); # t_relay(); }

I tried also the t_relay() function instead of the forward command, but the problem is the same.

Thanks in advance.

Bests,

Giuseppe
