[Serusers] How to handle ACK after stateless replies?

15 Mar 2004

Hi!

If the proxy replies stateless, how should the proxy handle the incoming 
ACK request?

e.g. an INVITE to an offline user:

if (!lookup("location")) {
    sl_send_reply("404", "Not Found");
    break;
}

The SIP client will respond with ACK to the 404 response. How shall I 
handle this ACK - just ignoring it?

BTW: Is it allowed to send stateless replies on existing transactions?
e.g:
t_newtran();
...
sl_send_reply(..);

thanks,
Klaus
