<DIV>So, if you're pointing to the IP addresses of the subscriber for example,
you lose all this URL if it goes down, is that correct?</DIV>
<DIV>Has anybody tried to do some sort of load-balancing? SLB (server load
balancing) for example with the http service in a CCM cluster?</DIV>

<DIV><FONT face=Arial size=2>Ah - I see. There are several schools of
thought there. By using IP address you eliminate the need and dependancy for
DNS, however, if that server that you are pointing to goes down, then so
does your service. By using DNS, you should be able to keep all those
services up and running. I'm not sure about the DNS caching on a phone, so
if a phone has already used a service and it goes to use the service again,
will it re-request the DNS entry again or use what it has in cache? If so,
does it time out? And if you figure this all out can you rely on it being
the same in the next release of software?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I think the general concensus has been to go
with IP addresses from what I've seen on the list.</FONT></DIV>

<DIV><FONT face=Arial size=2>Many of the services can be run on multiple
subscribers to provide redundancy, however, there are some services that
require access to the publisher. If the publisher goes down or the
synchronization between the cluster is lost you will lose some
services/features. I don't know if there is a full list, but it does
include the forwarding of phones and extension mobility. Basically, any
service that writes(?) to the database.</FONT></DIV>

<P>Hello,</P>
<P>is it possible to make some kind of redundancy with the services
activated in the CallManager?</P>
<P>We don't want to lose all this services when the server associated
fail...</P>
