Installing subscriber callmanager 7.0 failes

Level 1
Level 1


I faced strange problem today. I have CUCM 7.0 as a publisher. today I try to install subscriber with excact same version.

When installation reaches integration step with publisher, I enter publisher hostname, IP address and security password but validation failes.

I do following steps to fix a problem with no luck:

1- I reset security password in publisher using "pwrecovery" and "pwreset".

2- reboot publisher CUCM.

3- change hostname in publisher.

4- connect publisher and subscriber with cross cable.

I add subscriber IP address In "server" tab in CUCM publisher. I think everythink is ok. I install publisher ans subscriber many times but I don't know why this time this problem happens.

Only difference between this time and other intallations is that when I installed publisher, I enable DNS. I read some post about DNS problem. I also disable DNS on publisher but the problem doesnt fixed. I had both servers host name in DNS.

Any help will be appriciated.

If you have a cross-over cable between the CUCM pub and sub there is no way to resolve the publisher hostname via DNS. I have always used DNS in my installs but I do know that if there is a name resolution failure it will affect adding a new subscriber.
