Hi guys,
I have a problem with call forwarding (on busy or not answer).., the
call fall into the failure_route(1) block, and AVP checking and pushto
does its job.
Here a snipped of code of failure_route(1) (flag 27 means call fwd if
no answer):
if (isflagset(27) && t_check_status("408")) { # if fwd no
answer is set and reply msg is 408
if (avp_pushto("$ruri", "s:fwdnoanswer")) {
avp_delete("s:fwdnoanswer");
resetflag(27);
avp_print();
log(1, "LOG: --> appending new branch...");
if (!append_branch()){
t_reply("500", "Too many
branches?!");
drop;
}
log(1, "LOG: --> Calling route_6...");
route(6);
break;
Route(6) finally calls route(1), where t_relay is called.
But have a dns failure..and the call never is forwarded.

A question regarding this trouble.....Can I disable use_dns_cache ?
SER version is 0.9.7.
there is no DNS cache in version 0.9.x as I recall, but anyway, your
problem does not seem to be related to DNS, but to the UDP message
sending: SER fails to send out the UDP packet, "Operation not
permitted". Is there no firewall or routing problem at the proxy side?

What do you recommend?
If you need my ser.cfg I can paste it...
Thanks..
