Hello,

do you do record routing on server? The ACK should follow Route headers.

A network trace (ngrep, ethereal) will help to identify the cause for the problem.

Cheers, Daniel

Hi all

I have implemented the load balance in mode statefull, I obtained the next messages:

phone1 dispatcher sipserver phone2 --------INVITE--------> ----INVITE-----------> ----INVITE--------> <----100 TRYING---- <---100 TRYING---- <---100 TRYING---- <----180 RINGING-- <---180 RINGING--- <---180 RINGING--- <----200 OK---------- <----- 200 OK-------- <---200 OK-------- -------- ACK --------> --------- ACK -------->

You can see that the sipserver never sends ACK message to video_phone2. Is this correct?

Then I try the next, in the sipserver: if (method =="ACK"){ if (!t_relay()) { sl_reply_error(); }; return; }

But the sipserver doesn't send the message ACK at the phone2? Does some body know what it's wrong?
