Hi,<br><br>The SER version was updated, but only in the trunk of openimscore, and i had a working copy of a branch (with the old SER version) .<br>Now, i have checked out the trunk and i will test it soon.<br><br>Thanks,<br>

It looks like SER is compiled with all compilation flags for DNS failover... are these features set in the config file?<br>I guess you're using openIMS SER branch, isn't it? I don't know if it has been sync with latest SER
2.0 and I can not assure whether ser 0.10.99-dev53-tm_fixes has SRV failover support (which I think it does althought with maybe some bugs).<br><br>From the dig output I guess you're trying to load balance between the two servers responding for
scscf.open-ims.test, isn't it? <br>Can you please attach the log file section where SER is trying to send to this destination?<br><br>Thanks,<br>Samuel<br><br><div><span class="gmail_quote">2007/5/14, Mário Ferreira <

Hi,<br><br>
<p><span lang="EN-US">I am
interested in using SER DNS failover, but I am getting some problems.</span></p>
<p><span lang="EN-US">A failure
can be a 503 error response, ICMP errors or a timeout due to a not received
response.</span></p>
<p><span lang="EN-US">Does anyone
know if SER is able to detect these failures and then select an alternative
destination for the message?</span></p>
<p><span lang="EN-US">If the ICMP
errors can't be detected, can this be solved with timers?</span></p>
<span style="font-size: 12pt;" lang="EN-US">I turned on use_dns_cache and use_dns_failover, but
when the message fails to be delivered to the first destination,<br> SER never tries
the second destination, which was configured with DNS SRV.</span><br><br>regards,<br><span><br>Mário Ferreira<br>
