Has anyone attempted to load balance SER using Ultramonkey/ldirectord?
I've noticed all it does is pretty much NAT and send requests
accordingly, the trick I guess would be the NAT part. If the SIP headers
= myself, would there really be any issues? One problem I can foresee is
the possibility that loose routing would hit the wrong server. Just
wanted to ask around before I wasted time trying it out for myself :-)
Thanks

Ok, I've checked over my config and am going bananas. I cannot get a
"failover" scenario working. The first LCR load_gw is fine however
whenever a call fails (in this instance I am generating a 404) it never
sees the second priority. Thoughts?
I Dial 636561XXXX
I checked my logs, everything goes through just fine, get the 404 (per
failover test), it gets caught by the failure if statement and spits out
no more gateways..
lcr table (accounting for e164 and non)
+------------+----------+--------+----------+
| prefix | from_uri | grp_id | priority |
+------------+----------+--------+----------+
| +1636 | % | 2 | 1 |
| +1636 | % | 1 | 2 |
| 636 | % | 2 | 1 |
| 636 | % | 1 | 2 |
+------------+----------+--------+----------+
route[99] {
t_on_failure("2");
if(!load_gws())
{
sl_send_reply("500", "Internal server error, unable to
load gateways");
break;
}
log (1, "Running next_gw\n");
if(!next_gw())
{
sl_send_reply("503", "Service not available, no gateways
found");
xlog("L_INFO", "<%ru> <%br>\n");
break;
}
xlog("L_INFO", "Time %Tf RURI <%ru> \n");
t_relay();
break;
}
failure_route[2]
{
log(1, "Hit failure route 2\n");
if(method == "INVITE" && t_check_status("408|500|503|480|400|404"))
{
xlog("L_INFO", "NOTICE: Hit failure 2 and error status code\n");
if (!next_gw())
{
xlog("L_INFO", "ERROR: No more gateways for LCR failover
dropping call\n");
t_reply("503", "Service not available, no more gateways");
break;
}
t_on_failure("2");
# ...
t_relay();
}
}

something like this....
route[8] {
if (!load_gws()) {
sl_send_reply("500", "Server Internal Error - Cannot load
gateways");
break;
};
if (!next_gw()) {
sl_send_reply("503", "Service not available - No more gateways");
break;
};
t_on_failure("4");
if (!t_relay()) {
sl_reply_error();
};
}
failure_route[4] {
if (!next_gw()) {
t_reply("503", "Service not available - No more
gateways");
break;
};
t_relay();
break;
}

Heheh, we may actually test one of those F5network switches...i f we
don't come up with a fairly painless, bugfree, and most importantly
supportable solution. :-) I cannot code therefore I would be useless,
but I can safely say learning C is on my to-do list. We may however be
willing to contribute to a bounty, at the very least I'd be more than
happy to test :D

:-) Yes, layer 7 switch is of course nice. But then again, you need to
make
sure that you can price your services where people will buy them...
I wonder whether it is possible to gather some people interested in this
and
get something started on the development side. AFAIK, LVS struggles with
other UDP services too, so a ipvs UDP content analyzer would probably be
of
interest. I looked at the source code and I think the most difficult
thing
would be to extend the ipvs framework to allow a module to peak into the
packet (and not only the header). I don't know what kind of performance
penalties you get either.
I have seen several people being willing to sponsor development. We
could
hire somebody at http://www.rentacoder.com/ ;-)

Hi all,
Here is my confusion about SER supporting NAT transversal.
1. With only RTPProxy, what kinds of types of NAT can SER with nathelper transverse?
2. What's the difference between MediaProxy and RTPProxy?
3. If UA supports STUN, do SER need to configure nathelper to support NAT transversal? Just because I knew STUN protocol only process a few kinds of types of NAT, I want to know what advantage it will add if I configure SER with nathelper.
Thanks a lot!
