CUCM Cluster

Answered Question
May 31st, 2010

Hi Guys
I have configured a cluster with two CUCM, 1 Publisher a Subscriber.
How do they work with the concept of just doing my subscriber call control?

Because up till the time I did was the following:

On my Gateway connected to PSTN, I set the following parameters

SCCPs local FastEthernet0 / 0
SCCP ccm identifier 172.16.0.148 1
SCCP ccm identifier 172.16.0.147 2
SCCP
!
SCCP ccm group 1
associate ccm 1 priority 2
associate ccm 2 priority 1


ip dhcp pool VOICE
   network 10.10.10.0 255.255.254.0
   default-router 10.10.10.1
   option 150 ip 172.16.0.147 172.16.0.148
   domain-name mydomain.com
   dns-server 172.16.0.10 172.16.0.3
   lease 30

dial-peer voice 1000 voip
description (SUBSCRIBER)
destination-pattern [1-7] .. $
voice-class codec 1
voice-class h323 1
session target ipv4: 172.16.0.147
dtmf-relay h245-alphanumeric

dial-peer voice 1100 voip

So I believe my primary subscriber and TFTP and links are directed first to the 172.16.0.147 (Subscriber).

But when I check all my devices have been registered in Publisher (172.16.0.148)

My configuration is correct, anyone have any tips?

The GW config has absolutely nothing to do with where your phones register, that is defined by CUCM config.

What you need is a CUCM group in which you define the SUB as primary server and PUB as secondary.

Then assign this to the device pool from phones.

OK
Gateway indicated  to determine the control input chamada.Que prioritizes the PUB that is  correct?

I'll make the change in  my Device Pool and see what happens

Thank  you for your help
