I'm am attempting to return a 503 "Service

t_reply("503", "Service Unavailable");
However this results in:
ERROR:tm:w_t_reply: failed to send a t_reply to a message for which no
transaction-state has been established
Reading up on t_reply, it clearly states: "Sends a stateful reply
after a transaction has been established." So, I guess thats means
even though we have received the invite, and send 100 Trying back, a
transaction does not actually exist.
So, my question is, how do I tell the sending UAC that we are 5XX so
that it can stop sitting there waiting for session progress?
Hello,
you can send the reply statelessly:
sl_send_reply("503", "Service Unavailable" );
or statefully:
t_newtran();
t_reply("503", "Service Unavailable");
Before you can use t_reply, a transaction must be established. This
can be done explicitly calling t_newtran() or it will be do internally
by other functions like t_relay.
