Hello,
I run ser.0.9.6 and I can use
either
rewritehostport("1.2.3.4:5060");
or
rewritehostport("pstngw.foo.com:5060");
with t_relay() command on INVITE/PSTN handler in order
to route calls to a Cisco PSTN GW.
This works fine.
Is "DNS SRV queries" supported on ser.0.9.6 and is there a specific conf ?
thanx

Use rewritehost("pstngw.foo.com");
(If port is specified, DNS SRV is not used, ref. the RFC)

or alternatively use rewritehostport but exclude the port number. I had
this problem and the bottom line is you cannot specify the port number
if you want to resolver to try and look for SRV records.

thanks. This works Ok.
I have one more question :
My DNS SRV config is something like that :
$ORIGIN pstngw.foo.com.
_sip._udp SRV 1 1 5060 pstn1.foo.com.
SRV 1 1 5060 pstn2.foo.com.
I can load balance (50-50) with the above.
But if one of the GWs is down, then SER keeps on doing "load balancing 50-50" ,
so the ~50% of the calls are routed to GW that is down .
Is there a way to have a redundancy setup with DNS SRV only (with 50-50 load balancing) ?
Does this supported by SER's DNS SRV implementation (t_relay() ) ?
Or do I have to handle this issue with the t_on_failure() mechanism ?
thanx.

SER's CVS HEAD version has this fetaure...I guess you would have to
use t_on_failure and such...

ok thanks .
Is there any way to combine DNS SRV and t_on_failure() ?
With rewritehost("pstngw.foo.com") SER sends DNS SRV queries, so load balance is
Ok.
How I know the first IP that SER sends the INVITE, so I can use the 2nd IP in
failure_route[1] block ?
I mean, something like that :
# --- PSTN Handler ---
...
if (uri =~ "^sip:XXXXXXXXXXXX@") {
rewritehost("pstngw.foo.com");
t_on_failure("1");
route(1);
break;
};
...
failure_route[1] {
if ((!t_check_status("487")) &&
(!t_check_status("486"))) {
rewritehostport("pstn2.foo.com:5060");
append_branch();
route(1);
break;
};
}
Is there any way to determine that SER tried that IP (pstn1-gw or pstn2-gw),
in order to use the other one ?

Another approach would be to use the dispatcher module and specify
the IP addresses
on your own instead of using DNS.
Use Call-ID based distribution to set '0' containing the IPs for
gateways A, B, C in that
particular order.
Enable t_on_failure() and there use the same Call-Id based
distribution but with a changed
order of gateways, i.e. popping the first one and appending it to the
end so set '1'
would read B,C,A. That'll make sure for the same Call-ID a call will
always end up
on a different gateway for retries.
Cheers,
Hendrik

In ser CVS there was DNS cache and SRV failover support added recently.
It will do the failover automatically.
