<p class=MsoNormal style='margin-bottom:12.0pt'>Hi Adam,<br>
<br>
<br>
First of all thanks for your reply. At first, I have configured a CM group
(which i chose only secondary node as group member), then a device pool which
uses the brand new CM group. After doing these i have assigned my phone to the
new device pool. Everything went fine and my phone is up now.<br>
<br>
Here are my concerns, i don't have opportunity to get first node offline at the
moment, because it's being used consistently. What happens if i pull the LAN
cable of the first node? I'm going to try it this weekend. <br>
<br>
So should i think like "when i pull the lan cable of the first node, the
phones which are assigned to the second node will be up" <br>
<br>
What if they do not come up? What way should i use??<br>
<br>
Thanks for your help.<br>
<br>
Kind Regards.<o:p></o:p></p>

<p>Hi guys,<br>
<br>
I'm desperate on this.. We have a 3845 voice gateway attached to two 7800
series call manager servers. Here is the deal; i would like to integrate failover
feature within these two 7800. I've searched all over the cisco documentations
but no use...<br>
<br>
We already have an operating CUCM 6, besides yesterday i could manage to setup
second node. I can see the second node in CUCM 6 as subscriber in the cluster.
But when i pull out the first node's LAN cable, second one does not
automatically takes place as the first node and make a failover. All the ip
phones stuck, while trying to obtain IP address. Besides, when i give the ip
address (which was obtained when the first node is online) manually, the result
is the same, phones stuck. <br>
<br>
As i said, i couldn't find any detailed documentation how to make an operating
failover, the ones that i found was not enough for me to do the job.<br>
<br>
I am waiting for you guys to help on me.<br>
<br>
Kind Regards.<br>
