You need to relay REFER to the other UA, SER should not be involved.  The NOTIFY should not be stopped either, but relayed.
Normally, REFER should be t_relay'ed directly to the UA, but you may have some NAT issues as the UA never answers.  Look at the REFER and see where it goes.

Hi all,
 
Is it deal with the ctd.sh script? Configure inside loose_route()?
 
I can get the REFER message but no responses (202 Accepted and NOTIFY) to it.
So I send reply 202 inside loose_route if method=REFER.
 
After that, inside ethereal, I can see the code 202 response to REFER.
However, It send REFER again and after a while 408 TIMEOUT.
 
This is what i configured:
 
if(loose_route()){
    if(method=="BYE"){
        setflag(1);
        setflag(2);
    };
 
    if(method=="REFER"){
        sl_send_reply("202","Accepted");
    };
 
    t_relay();
    break;
};
 
 
 
 
Please help.
 
Thanks in advance

    Could you give me some clues how to do that or some references about it? I really have no idea.
 
Thanks again.

Well, yes, you have to route REFER, and you should allow NOTIFYs.

Hi all,
 
I have some question about call transfer.
 
When I press transfer key follow by the new destination and "send", I can see the REFER message inside ethereal but after that request timeout error(408).
 
Inside REFER message, i can see the refer-to and referred-by values are correct.
Do I need to add something inside ser.cfg to enable call transfering? Because I cannot find any sample codings regarding ser call transfer.
 
 
 
Thanks for any help.
